without this fix, the scope may not have been initialized which threw the following exception:

onDestroy is not called when navigating to the next activity or bringing the app to background. That's why the adapter was not set to null and all messages were added another time the next time the activity comes to foreground. With this fix, the adapter is set to null in onStop.
All in all, the adapter handling may not be the best, but will be replaced by Compose anyway..

userManager.currentUser was called too often. I was not able to prove that a bug is related to it but i think it may fix some hidden bugs.
CurrentUserProviderImpl is now used throughout the code to access the current user.
userManager.currentUser is only used from CurrentUserProviderImpl whenever the _currentUser was null (should only happen on app startup)
To avoid multiple initialization of CurrentUserProviderImpl it was changed to be a @Singleton
The handling should soon be replaced with coroutine flows. However for the v21.0.0 release it's still done with RxJava to avoid bugs.
