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 a new OpenGroupServerIdLookup to make it easier to get a database id via an open group server id
Added a migration to generate the above data
Updated the handleCompactBody method to stop early if there are no messages to delete (would previously enumerate all interactions regardless)
Updated the handleCompactBody to fetch the mapping for the deleted message so we can avoid enumerating all interactions
Fixed a possible divide by zero error
Cleaned up some of the id blinding methods (ie. removing handling for impossible error states)
Added unit tests for the new Sodium methods (used for id blinding)
Added unit tests for some of the shared code
Added unit tests for the MessageSender+Encryption extension functions
Added unit tests for the MessageReceiver+Decryption extension functions
Updated the unit test key constants to be consistent with the SOGS auth-example keys for consistency
Updated the HomeVC to count the threads with unread messages using the TSMessageRequestGroup instead of using the UnreadDatabaseView
Removed the OWSMessageUtils 'unreadMessageRequestCount' method
Added the ability to mock the identity manager (ie. return a mock key for the users key)
Swapped the Test Nonce16 & Nonce24 classes for Mock ones
Fixed an issue where the ContactUtilities call from the OpenGroupManager wasn't injecting the dependencies
Added unit tests for the handleDirectMessages and isUserModetatorOrAdmin methods
Added tests for the OpenGroupManager handleMessages logic
Updated some logic to do an optional unwrap instead of a forced one to prevent the code from crashing when running unit tests
Fixed some tests which were flaky (could fail if other tests ran at the same time on other threads)
Fixed a minor potential bug where a message with no sender data wouldn't get deleted (shouldn't be dependant on the sender value being populated)
