Lorenzo Colitti 83fa2588f6 Make ConnectivityServiceTest a bit more readable.
1. Make TestNetworkCallback a bit smarter and rename it to
   SingleUseNetworkCallback. This allows us to get rid of all the
   calls to TestNetworkCallback#getConditionVariable.
2. Delete the commented out code that used to test a
   ConnectivityService model that has not been used since KK.
3. Remove unused imports, etc.
