[[bugzilla:53600]] "@unkb can't unban user kicked from channel"

[Technical-13]

See: https://bugzilla.wikimedia.org/show_bug.cgi?id=53600
@Unkb returns "Sorry but I don't see this user in a channel"
Problem is, if the user was kicked from the channel and is banned, than they
can't be in the channel for @Unkb to work.
