Dan Williams 4d2957b3ae settings: fix NMSettingsConnection D-Bus Remove signal emission 
We can't unregister the object with the bus during the remove signal,
because dbus-glib doesn't send the signal out over the bus until late
in the signal emission process, after we've unregisterd the object.
Thus the signal doesn't go out.  Fix that.
