Use integer coordinates for Actions.pointerMove.

The 2 tests were failing on wpt.fyi because the coordinates passed to Actions.pointerMove were not integers (like on local run). Since Actions.pointerMove expects integer coordinates, the tests were failing with an exception.
Use Math.ceil on coordinates passed to Actions.pointerMove. Apply memory leak fix.
