feat: 1:1 proteus is not migrated to MLS - WPB-17393

WPB-17393 [iOS] Should-be MLS Conversation created as Proteus and not migrated to MLS

Issue

We have an issue with one user that his 1:1 with a user from another team is still proteus on iOS, however it's MLS on Web. The result is a conversation on Web (and Android for another user) with a history, but an empty proteus conversation on iOS.

The logs from DD say that tis conversation resolve 1-1 conversation failed: alreadyMigrated. From all the logs and the fact that MLS conversation exists, but for some reason doesn't show up in the conversation list, we suspect that 1:1 MLS conversation is marked as migratedToMLS, but otherUser.oneOnOneConversation is still Proteus.
Why or how this happened is unknown. Most likely the conversation was migrated, but something overrode otherUser.oneOnOneConversation and set it back to the proteus conversation.
In this PR I added one more condition to trigger messages migration and MLS conversation linking:
if mlsConversation.migratedToMLS is false and otherUser.oneOnOneConversation is not mlsConversation,
we should attempt to migrate.
Also, since we have an insane amount of error logs like resolve 1-1 conversation failed: alreadyMigrated which are not an error but rather info, I changed their logging a bit.
