Receiving OMEMO messages causes duplicate fallback warning

[Gabatxo1312]

Expected Behavior

I want to be able to receive OMEMO-encrypted messages without message duplication (where Profanity says that the recipient does not support OMEMO).

Current Behavior

When I send a message, the other person receives it with the small lock icon indicating that it is correctly encrypted with OMEMO. However, when I receive a message, I always get a duplicate message:

21:27:52 * me: Test
21:27:52 - me: I sent you an OMEMO encrypted message but your client doesn’t seem to support that. Find more information on
           https://conversations.im/omemo

Steps to Reproduce (for bugs)

1. /omemo start [email protected]
2. /omemo trustmod blind (to check if it was a trust-key issue)
