When members click a link in an email, Ghost updates the member's
`last_seen_at` timestamp, but it should only update the timestamp if the
member hasn't yet been seen in the current day (based on the
publication's timezone).
Currently there is a race condition present where multiple simultaneous
requests from the same member (if e.g. an email link checker is
following all links in an email) can cause the `last_seen_at` timestamp
to be updated multiple times in the same day for the same member. These
additional queries add a significant load on Ghost and its database,
which can contribute to the exhaustion of the connection pool and
eventually requests may time out.
The primary motivation for this change is to avoid that race condition
by adding a lock to the member row, checking if `last_seen_at` has
already been updated in the current day, and only updating it if it
hasn't.
Another beneficial side-effect of this change is that it avoids locking
the `labels` and `newsletters` tables, which are locked when we update
the `last_seen_at` timestamp in the `members` table currently. This
should improve Ghost's ability to handle a large influx of requests to
redirect endpoints (confirmed with load tests), which tend to happen
immediately after a publisher sends an email.

This is a revision of a previous commit, that broke the browser tests
because changes in the data generator (requiring bookshelf had side
effects).
This adds a new way to run all tests with enforced numeric ObjectIDs.
These numeric ids cause issues if they are used withing NQL filters. So
they surface tiny bugs in our codebase.
You can run tests using this option via:
NUMERIC_IDS=1 yarn test:e2e
Removed some defensive logic that could be explained by this discovered
issue.

We're rolling out new rules around the node assert library, the first of which is enforcing the use of assert/strict. This means we don't need to use the strict version of methods, as the standard version will work that way by default.
This caught some gotchas in our existing usage of assert where the lack of strict mode had unexpected results:
- Url matching needs to be done on `url.href` see aa58b354a4
- Null and undefined are not the same thing, there were a few cases of this being confused
- Particularly questionable changes in [PostExporter tests](c1a468744b) tracked [here](https://github.com/TryGhost/Team/issues/3505).
- A typo see eaac9c293a
Moving forward, using assert strict should help us to catch unexpected behaviour, particularly around nulls and undefineds during implementation.

The old email flow is no longer used since we introduced the email stability flow. This commit removes the related code and tests. The general test coverage decreased a bit as a result, because the old email flow probably had a high test coverage. The new flow is in separate packages, so it couldn't contribute to a higher test coverage (but it does have 100% unit test coverage).
fixes https://github.com/TryGhost/Team/issues/2282
Added a new email service package that is used when the email stability
flag is enabled. Currently not yet implemented so will throw an error
for all entry points (if flag enabled).
Removed usage of `labs.isSet.bind` across the code, because that breaks
the stubbing of labs by `mockManager.mockLabsEnabled` and
`mockManager.mockLabsDisabled`. `flag => labs.isSet(flag)` should be
used instead.
All email depending tests now disable the `emailStability` feature flag
to keep the tests passing + make sure we still run all the tests for the
old flow while the email stability package is being built.

- The codebase has ambiguous behavior with OPTIONS request. Adding tests covering edge cases for all possible variations of OPTIONS responses is the first step to solving cahceability of these requests.
- The obvious question if you look into the changeset itself would also be: "WTF did you do with test suite naming? What are these changes in admin and click tracking suites? You having a bad day Naz?". The answer is "yes" (╯°□°)╯︵ ┻━┻
- On a serious note. I've introduced multiple hacks here that should be fixed:
1. Forced test suite execution order for options request - extreme blasphemy. This was last resort decision. I went deep into trying to fixup the server shutdown in the "admin" test suite, which cascaded into failing "click tracking" suite, which has shortcomings on it's own (see notes left in that suite)
2. Exposed "ghostServer" from the e2e-framework's "getAgentsWithFrontend" method. Exposing ghostServer to be able to shut it down (or do other manipulations) was one of the pitfalls we had in the previous test utils, which ended up plaguing the test codebase. Ideally the framework should only be exposing the agents and the rest would happen behind the scenes.
- To fix the hacks above I've raised a cleanup issue (https://github.com/TryGhost/Toolbox/issues/471). I'm very sorry for this mess. The issue at hand has very little to do with fixing the e2e framework, so leaving things "as is".

This tests the full flow of publishing a newsletter, and then checking
that clicked links will increase the click count, generate events for
the member which clicked the link as well as the redirects contain the
correct query params.
