Remove QSPanel bounds after expansion animation.

QSPanel#setClipBounds is called during the expansion animation of QS,
but were not cleared after full expansion. Tiles added in the
customization flow properly expanded the QSPanel's size, but were not
drawn to the screen due to the stale view bounds. Clearing these bounds
also ensures that screen orientation changes properly redistribute the
tiles (e.g. 3x4 -> 3x4).
