Also update active network state in response to manager events

NetworkChangeNotifierChromeos currently relies on service
property signals from shill to handle state changes on active
network once the active network has been added. Under certain
circumstances, we may not get correctly notified of these
service-specific signals.

So, be a bit more robust and have NCNCros opportunistically update
the active network state from manager updates instead
of just relying on service signals.
