Kick reason of another user isn't getting shown

1. Enter a MUC (as moderator)
2. Kick a user (using another client, since Cyclops doesn't support kicks, yet)

**Expected result:** the kick reason should be shown after a user is kicked.
**Actual result:** kick reason isn't visible.

We show the kick reason if the Cyclops user themselves gets kicked, but we doesn't if there's any other user.
