Cannot --connect if overriding knetworkmanager

[mvidner]

(Reported by muimota@freenode)

If one calls -C and knetworkmanager is running, knm lets go of NetworkManagerUserSettings ownership (and reacquires it when cnm exits), as seen from NameOwnerChanged signals. But apparently NM itself cannot handle that and logs:
