Non-continuous SpeechRecognition returns multiple results, eventually gets
stuck returning the same utterance

Reviewed by Sihui Liu.
In non-continuous mode, our SpeechRecognizer behavior differs greatly from
other browsers and the spec: it returns multiple results, and returns all
utterances from the session in confidence order on each new recognition,
resulting in the "most confident" transcript getting "stuck" after a while.
* Source/WebCore/Modules/speech/cocoa/WebSpeechRecognizerTask.mm:
(-[WebSpeechRecognizerTaskImpl speechRecognitionTask:didFinishRecognition:]):
Explicitly stop the session once we get one recognition result when in
non-continuous mode,
because this is not communicated to the Speech framework in any other way, so it
just keeps happily recognizing.
Also, avoid dispatching extraneous recognitions while we're cancelling,
or, more importantly, when we're stopping in non-continuous mode.
