Subject: [PATCH] login: fix memory-leak on DropController()

Our bus-name watch helpers only remove a bus-name if it's not a
controller, anymore. If we call manager_drop_busname() before
unregistering the controller, the busname will not be dropped. Therefore,
first drop the controller, then drop the bus-name.
