* SUMMARY
We recently changed "Stop Recording" button to wait for a "recordingStopped" event from the backend to stop. However, this can produce a very large delay between the time the user clicked "Stop Recording" to when the frontend gets the event. This is especially bad in remote debugging, e.g. with iOS.

We should have the UI immediately stop recording and ignore future events. This was the behavior before r171195.

* STEPS TO REPRODUCE
1. Load <http://apple.com> in remote target
2. Inspect remote target
3. Reload via inspector
4. Quickly click the record button to "Stop Recording"
  => recording continues for a couple seconds
