Explicitly reset the speech state when closing the app launcher.

Explicitly reset the speech state when closing the app launcher.

If the launcher was in the middle of speech recognition when it was
closed, it get's stuck in the RECOGNIZING state which prevents
hotwording from working in the future. Explicitly reset the state so
this doesn't happen.
