Crash - Note.getScrollY() on a null object reference

This issue respects the following points:

• I have read the FAQ
• I have searched for existing issues
• The issue affects the Notes Android app, neither the Notes server app nor the Nextcloud Android app.

Describe the bug

I don't have clear steps but I believe this occurred switching back to one of the app's windows. Only seen with 4.2.0. I thought the stack trace might be useful anyway.

My gut feeling is maybe it was switching back to the window which had a note open, but the window had dropped out of memory? It's a guess, based a little also on the stack trace.

In which case it would be:

1. Open Notes
2. Open a note, that for some reason now creates its own window
3. Do a whole bunch of other things, pushing the app out of memory
4. Switch back to that single note window
5. Maybe??

If I see it recurring I'll update the steps. If not useful the issue can be deleted.

Start with BaseNoteFragment.onNoteLoaded at line 274 and follow the call from onViewCreated, then inspect NoteEditFragment.onNoteLoaded at line 157. Reproduce the reported window and memory-pressure scenario if possible; done means returning to the note window no longer crashes when the loaded Note is unavailable.
