Crash while switching to hardware keyboard: `IllegalStateException: Fragment NoteEditFragment [...] not attached to a context`

Describe the bug
Whenenver I switch from the software keyboard (default Google keyboard app) to my hardware keyboard (Logitech G910, connected via Bluetooth) the Nextcloud Notes application crashes showing a stack trace. The keyboard switch happens by enabling Bluetooth mode on the keyboard which results in the keyboard connecting to the Android tablet triggering it. Switching from hardware to software keyboard works without any problems. If there's no active note opened for editing, there is also no crash.

To Reproduce
Steps to reproduce the behavior:

1. Open a new or existing note in Nextcloud Notes
2. Connect a keyboard via bluetooth
3. See the error message

Expected behavior
The app continues to function without a crash while switching to hardware keyboard.

Screenshots
No screenshot since it instantly shows the posted exception message.

Start with NoteEditFragment.onNoteLoaded at NoteEditFragment.java:165 and trace the callback from BaseNoteFragment.onViewCreated at BaseNoteFragment.java:134. Reproduce the crash by switching to a Bluetooth hardware keyboard while editing a note, then verify that the note editor remains usable and no detached-fragment exception occurs.
