Unable to send unencrypted after importing settings with no OpenPGP App installed

[silmaril42]

Expected behavior

I should be able to send an unencrypted email.

Actual behavior

Email cannot be sent. Red lock symbol is shown, due to PGP provider unavailable.

Steps to reproduce

1. Export K9 settings from a phone with OpenPGP provider installed and integrated into K9.
2. Import those settings on a phone with no OpenPGP provider installed.
3. Try to send an email --> not possible.

Workaround

1. Go to global settings
2. Tap on "OpenPGP App" --> Nothing is selected here
3. Explicitly select "no selection"

Now K9 is really configured not to use OpenPGP and sending (unencrypted) emails works again.

Environment

K-9 Mail version: 5.600

Android version: 8.0.0

Account type: IMAP

This seems similar / related to #1153 and the other issues mentioned there.
