Removed the legacy Theme code (replaced with SessionUIKit equivalents)
Removed the OWSOrphanDataCleaner (unused)
Removed the OWSReceiptType_Delivery from the OWSOutgoingReceiptManager (unused)
Removed the TSStorageKeys and TSStorageHeaders files (unused)
Removed the LKMessageIDCollection (unused - only had methods for deleting data from the collection)
Removed the OWSPrimaryStorageTrustedKeysCollection and OWSIdentityManager_QueuedVerificationStateSyncMessages (unused)
Removed collections and notifications from OWSProfileManager (unused)
Wrapped the force sync calls within their own Storage.write blocks to ensure they have the latest data and aren't accessing a transaction completed in a different thread
Reverted a number of the unneeded changes
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 the "block" button would appear in the NoteToSelf swipe menu
Removed the OWSBlockingManager and supporting files
Removed a number of unused classes and methods
Refactored the BlockListUIUtils to Swift
Added an error state to the OpenGroupSuggestionGrid
Fixed a bug where the settings button wouldn't appear for the sender of a message request once approved
Fixed a bug where the ConfigurationMessage was getting generated before the contact state was persisted to the database in the message request flow causing odd behaviours (now generating the ConfigurationMessage within the same transaction)
Fixed a bug where sending a message to an existing message request thread once the message requests item has been hidden would show the message requests notification and trigger the section to re-appear on the home screen
Fixed a bug where blocked contacts weren't getting excluded from the contacts list in the configuration message
Fixed a bug where the notification count could be increased for message requests
Fixed a bug where an approved contact could be 'unapproved' due to an order of execution issue when generating the config sync message
Fixed a check to avoid registering for push notifications when on the simulator (old check didn't cater for M1 Macs)
Moved the 'hasHiddenMessageRequests' into the group user defaults so it can be accessed within the notification extension
Added code to handle an edge case where an old client could incorrectly un-approve a contact via a legacy configuration message
Added some missing localised strings
Prevented 'Read' and 'Typing' indicators from functioning on Message Requests
Prevented link previews on the first message of a message request
Added a confirmation alert when trying to clear all message requests
Added a confirmation alert when trying to delete a message request
Added an empty state to the MessageRequestsViewController
Updated the back behaviour of the ConversationVC to behave more nicely with approving/declining message requests
Updated the OWSBlockingManager to also update the stored contacts 'isBlocked' flag to match
