Fixed an bug where config messages could be processed in the wrong order
Tweaked the behaviour or removing threads (this would cause issues with future config-based settings changes that live on the thread getting lost)
Started writing up wrappers and unit tests for group config types
Refactored some duplicate batch & prepared request code to be more generic and reusable
Renamed a number of legacy closed group functions to have the term 'legacy' in them for ease of coding
Added libSession-util as a submodule and wired into build
Updated the logic to run migrations when returning from the background as well (since we will have feature-flag controlled migrations it's possible for a "new" migration to become available at this point)
Fixed an issue where the 'Note to Self' conversation could appear when linking a device for a new user
Fixed an issue where the app would process the ConfigSyncJob before completing onboarding
