Verify message comes from loginIframe

Browse source 
In the current implementation a message coming from any window on the same origin may cause the refresh token to be cleared.
In my case, messages generated by a chrome extension were causing the application to logout unexpectedly. With additional condition only messages coming from the login iFrame will be processed. Another suggestion would be changing the condition `event.data != "unchanged"` to something more specific.
