Fix Android peer connection client instrumentation tests.

- Updated Java VideoRenderer removes setSize() from video renderer interface.
Remove no longer valid test, which requires setSize() call before any
frame can be rendered.
- tries to run private member of InstrumentationTestCase class.
Workaround it by renaming private loopback test method.
