Previously JingleSession unit tests were using real authenticators. Here
I changed them to always use FakeAuthenticator and added new tests for channel 
authentication in v1_authenticator_unittest.cc . Also, to make new tests pass,
fixed session-terminate message handling in JingleSession to return correct 
error code.
