Make Chromoting browser tests pass again

Make Chromoting browser tests pass again

Summary of changes:
1. Fix a bug in identity.js that breaks first run scenario of the v2 app,
   Previously, we are resetting the deferred object (the list of listeners)
   when auth is failed even when interactive is set to false, which always
   happened on first runs.  At a result, when auth is completed, the listeners
   are not notified.
   This CL only clears the deferred object after it has notified its listeners.
2. Fix a missing parameter in session_connector_impl.js that causes It2Me to fail
   to connect.
3. Changes it2me_browser_test.js to match the changes in the identity API.

BUG=462708
