* Change ComposeOptions.mentionedUsernames to be Set rather than List
We probably don't want repeated usernames when we are writing a post

callers. The only disadvantage is lack of order but it shouldn't be a
problem.

It it useful for nullable LiveData's. I think we cannot differentiate
between value not being set and value being null so I just added the
variant without null check.
