Fix exception when deselecting person (EXPOSUREAPP-6003)

[ralfgehrer]

Steps to test

• Open locations or persons
• Select an existing item
• Click in the notes field, so the cursor is shown
• Deselect the person or location, selected in step 2

Expected result:

• No exception

Additional Remarks:
When editing notes, the soft keyboard shows up. If another entry (e.g. duration) is edited afterward, the soft keyboard should be hidden.

I ran through the repro steps from issue #2703 :

1. Open locations or persons
2. Select an existing item
3. Klick in the notes field, so the cursor is shown
4. Deselect the person or location, selected in step 2

on the same device mentioned in the issue report (Samsung Galaxy A5 2017 with Android 8) and there is no longer an error with the fix in this PR. I also successfully checked on a Google Pixel 3a emulator with Android 11.
