- moves the `entities.decode()` step to the `LinkReplacer` class so that
it's applied to all links, not just the ones that are replaced in the
email service
- adds a test case to `LinkReplacer` to ensure that the
`entities.decode()` step is applied to all links correctly, decoding any
URLs with HTML entities in them

fixes https://github.com/TryGhost/Team/issues/2666
- Somehow occurrences of `&map_` got replaced with `↦`
- Disables escaping &, ', " and other HTML characters when not needed
(escaping is already handled by mobiledoc/lexical)
- Bumps unit test coverage of link replacer to 100%

- Added database storage for link redirects and click events via repositories (hides away database layer) defined in the wrapper services
- Added LinkClickRepository to store click events to database
- Added LinkRedirectRepository to store link redirects to database
- Added PostLinkRepository to link LinkRedirects with posts
- Renamed link-replacement package to link-replacer, and made it dependency less (it only replaces links now, doesn't do anything else)
- The link-tracking service has a new `addTrackingToUrl` which returns a new URL that includes tracking. The new `addRedirectToUrl` method does the same but without tracking for now.
- MEGA service now uses the link-replacer to replace links in the emails using a combination of different services (member attribution + link-tracking service)
