fix(feedback): Track ownership in imperative shake API

enableFeedbackOnShake now records whether it actually started the
listener (using the boolean returned by startShakeListener).
disableFeedbackOnShake only stops the listener if it was the one that
started it, preventing it from interfering with a listener owned by
FeedbackWidgetProvider.
