Move all database queries off the ui thread & add a ViewModel for MainActivity (#4786)
- Move all database queries off the ui thread - this is a massive performance improvement - ViewModel for MainActivity - this makes MainActivity smaller and network requests won't be retried when rotating the screen - removes the Push Notification Migration feature. We had it long enough, all users who want push notifications should be migrated by now - AccountEntity is now immutable - converted BaseActivity to Kotlin - The header image of Accounts is now cached as well
