Fix data network type notifications.

These trackers have two copies of the network type: newSS and newNetworkType.  I think thats wrong,
but this was the smaller change on code that will hopefully be refactored soon.

On radio_off we were making a new, empty newSS but not clearing newNetworkType so it
still thought we were on 3G and when we reconnect and get 3G state changes new==old and we don't
send the update.  In this fix I reset newNetworkType every time we apply it to networkType.
