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.

currentConversation was not yet initialized in ChatActivity.
In the future this may be better handled via StateFlows. For now it's solved via arguments.
Without the fix, this NPE appeared:

the bug was, that the sent text was overwritten with "" in restoreState.
With this fix the saved state is only applied when the input field is empty (which means there was nothing shared)
