device: Unwatch names when removing them

Browse source 
If a device is unplugged/destroyed while a client is using it, then we
would still end up watching the name. The vanish notification will then
access the destroyed FprintDevice object.

Fix this by unwatching the bus name when removing the client entry from
the dictionary.
