dbus: Fix D-Bus network and BSS object registration/unregistration

Browse source 
Do not try to unregister BSS objects twice (the latter one with invalid
path) and make sure all network objects get added and removed properly
(the ones read from configuration file were not being registered, but
were tried to be unregistered).
