Sync Settings (#2478) * Sync Settings * Added valueHandlers and Database singleton Some issues remain, need a way to comparing incoming sql.DB to check if the connection is to a different file or not. Maybe make singleton instance per filename * Added functionality to check the sqlite filename * Refactor of Database.SaveSyncSettings to be used as a handler * Implemented inteface for setting sync protobuf factories * Refactored and completed adhoc send setting sync * Tidying up * Immutability refactor * Refactor settings into dedicated package * Breakout structs * Tidy up * Refactor of bulk settings sync * Bug fixes * Addressing feedback * Fix code dropped during rebase * Fix for db closed * Fix for node config related crashes * Provisional fix for type assertion - issue 2 * Adding robust type assertion checks * Partial fix for null literal db storage and json encoding * Fix for passively handling nil sql.DB, and checking if elem has len and if len is 0 * Added test for preferred name behaviour * Adding saved sync settings to MessengerResponse * Completed granular initial sync and clock from network on save * add Settings to isEmpty * Refactor of protobufs, partially done * Added syncSetting receiver handling, some bug fixes * Fix for sticker packs * Implement inactive flag on sync protobuf factory * Refactor of types and structs * Added SettingField.CanSync functionality * Addressing rebase artifact * Refactor of Setting SELECT queries * Refactor of string return queries * VERSION bump and migration index bump * Deactiveate Sync Settings * Deactiveated preferred_name and send_status_updates Co-authored-by: Andrea Maria Piana <andrea.maria.piana@gmail.com>
