tst_qtooltip: Move cursor away from tooltip.

When executing the test in a sequence (as done by make check after
tst_qstackedlayout), tst_QToolTip::task183679 often fails since
apparently the tooltip is hidden when the cursor is near it.
Move to the cursor to the right corner of the widget to fix this.
