[Media Router] Remove obsolete code from media_router_bindings.js

- Remove unused functions onRouteResponseError/onRouteResponseReceived
- Remove redundant argument from onRoutesUpdated. Note it can be
further simplified by removing the input arg if we end up not needing
a MediaSink object in a MediaRoute.
