core: use wrappers for DBus object registration/unregistration

Browse Source 
When providing a service on the bus daemon and a private connection,
we'll need to track objects so we can register them with the
private connection too.  Thus all registration/unregistration
calls have to go through the NMDBusManager, not straight to
dbus-glib.
