Fix test failures with Robolectric 4.9

1. Use legacy LooperMode for tests explicitly, because recent
   Robolectric releases switch to use PAUSED mode default. Before these
   tests migrate to PAUSED mode, they use LEGACY mode to pass tests.
2. Migrate Assert.assertThat to Truth.assertThat to avoid using removed
   APIs.
3. All build.gradle use the same robolectricVersion except
   transport-backedn-cct because Robolectric 4.8+ has compatibility
   problem for TelephonyManager with low compile/targetSdkversion.
4. Remove unused exclude protobuf-java from Robolectric.
5. Add necessary protobuf-lite dependency on classpath for
   some ktx modules' tests.
