Fix expectCallback does not fail when no callback received
This hides 3 bugs where,
1. In Android S, onNetworkRequested is no longer broadcasted
by ConnectivityService in any condition. However, the test
still passes since assertion does not fail when no callback
received. Ignore the test on S+ devices since the behavior
changed on S or later devices.
2. Test network agent is not registered, but the test still
passes.
3. Test network agent does not fulfill the request that kept
the network up, so the test fails since the test network
is not needed and be torn down.
Test: android.net.NetworkProviderTest on R/S device
