plugin XEP-0384: update to latest python-omemo + better trust management:
- python-omemo minimal version is now 0.11.0
- `undecided` devices are now handled, fixing the "accept all or none" issue: if a device
is `undecided`, the trust manager will be shown with the missing devices before sending
the message.
- `untrusted` devices are discarded
