nick-dropdown is updated even if nickchange fails
I just tried to change my nick from "penny|wise" (old) to "pennywise" (new) with that nick-dropdown-selector next to the input line.
Freenode sent me that answer:
* 438 pennywise #quassel-announce Cannot send to channel so cannot change nicks
Sput said, that's a freenode feature, but:
if the nickchange fails (like in that 438-response), the nick-dropdown should not select the "new" nick, but rather switch back to the "old" one.
Issue #492 could be related to this.
