Fixes the following issue:
In RideauViewController, it has an issue that ViewController does not dismiss itself when the user interrupted swiping down animation.
At that time, RideauInternalView won't call the handler that tells what the snap point did change.
Currently, RideauViewController performs dismissal of itself if RideauInternalView's snap point has been changed to hidden point.
It fixed RideauInternalView tells view controller the changed snap point correctly.
