Fixed a couple of issues around the duplicate messages handling
Fixed a few issues with ClosedGroup polling and ClosedGroup control message handling
Started working through updating the MediaGallery
Tested and fixed a couple of issues with the disappearingMessages job
Added a simple dependency system for jobs (primarily for the AttachmentUploadJob, but will likely be others later)
Setup the AttachmentUploadJob again (looks like there are cases which use it)
Prevented a possible infinite job deferral loop from causing the app to crash (the loop is still technically possible but the app will continue to run now)
Updated the interactions unique constraints based on testing and discussions around how the serverHash works
Deleted the legacy ReadReceipt handling (now managed via the 'interaction.wasRead' flag and 'SendReadReceiptsJob')
Deleted the unused SSKIncrementingIdFinder
Fixed a few job migration issues
Fixed an issue with the closed group key pair management (wasn't storing keys correctly)
Refactored the OWSSound (now Preferences.Sound)
Added the logic for the AttachmentDownloadJob and enabled jobs to be cascade deleted via interactions
Optimised the HomeViewModel database observation query (fetch specific columns so changes outside those don't trigger updates)
Updated to the latest GRDB (ran into a deadlock which should be fixed in a newer version)
Added migrations for contacts and started working through thread migration (have contact and closed group threads migrating)
Deprecated usage of ECKeyPair in the migrations (want to be able to remove Curve25519Kit in the future)
Updated the migrations so they can specify whether a configuration sync is required
Moved the config sync logic into a MessageSender extension (makes far more sense than AppDelegate)
Fixed a bug where the ShareVC was triggering the 'versionMigrationsDidComplete' twice
Removed a couple of imports for files that had been deleted
Fixed an issue where sharing form Safari without adding comments would result in an invalid message getting sent.
Fixed a crash when sharing plain text from safari.
Fixed a crash when localising 'OK' (key and value can't be the same when using the new extension).
