Show app widget resize frame after launcher state change

When this bug occurs, the resize frame coordinate is incorrect because
the launcher state animation has not finished when the drag view
finishes animating back to its original position.

Test: Quickly long press and release a widget from the home screen.
      Observe the resize frame is correctly shown around the widget.
