Gajim update invalidates encryption settings
Steps to reproduce:
- Configure gajim to encrypt messages using OMEMO to a specific contact
- Update Gajim to 1.3.1
- Restart Gajim, update the plugins
- Try to send a message Expected outcome: the message is encrypted, encryption settings are "OMEMO" Actual outcome: the message is not encrypted, encryption settings are "unencrypted"
This is a security issue, because users might send messages thinking they're going to be encrypted, unaware of the fact that the upgrade reset the encryption settings.
