Reset the moveAnimator prop after a move animation (#396)

* Reset the moveAnimator prop after a move animation

If `moveAnimator` isn't null, `FloatingPanelPanGestureRecognizer.touchesBegan`
detects `began` state quickly so that it doesn’t allow to work a tap gesture or
tap action in a panel.

Resolve #392

* Add 2 buttons in DebugTableViewController
