no issue
Bookshelf by default returns an empty model when requesting .related('email') for a post without an email. So we need to be a bit smarter to know if a post has an email or not. This fixed an issue where we always showed 'published and emailed' instead of 'published only'.
Since this change also included some changes to test helpers, it also made some changes to the email service because coverage dropped below 100% as a result of fixing the .related method mocking. Ideally we want to move test test helpers to a seperate package in the future.
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.
