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
