LoginPromptManager.showLoginPromptIfAbsent throws an exception

[jakub-gil]

We have couple hundreds of crashes with an exceptions

Fatal Exception: java.lang.IllegalStateException
FragmentManager has been destroyed

and

Fatal Exception: java.lang.IllegalStateException
Can not perform this action after onSaveInstanceState

It seems like those are thrown after fragment is stopped, and just then Client.requestLoginPrompt tries to invoke function LoginPromptManager.showLoginPromptIfAbsent. Exception is thrown at this line initializeLoginPrompt(loginPromptConfig).show(supportFragmentManager, fragmentTag).

Can you add couple checks for FragmentManager to not crash there? We implemented temporary solution, but those should be fixed at the core.
