Fix rate, pitch, and volume from web speech synthesis API to extensions.

Fix rate, pitch, and volume from web speech synthesis API to extensions.

The web speech synthesis API was correctly passing through an utterance's
rate, pitch, and volume to native TTS, but not to extension-based speech.
This fixes the bug, and I filed another bug to clean up the redundancy that
led to this bug being there.
