Adam Newman 5178a9d07a Observe NetworkCallback instead of polling ...

Switch from polling for the first connected WiFi network to observing
the currently connected WiFi network and associating that with the
preference at the time the preference is created or updated.

Whenever the ConnectedAccessPointPreference is removed or UI is stopped
unregister the callback.
