Bug 1093431 - Intermittent browser_styleinspector_tooltip-closes-on-new-selection.js; r=test-only

Make sure the test removes the toggling on hover of the rule-view tooltip to avoid intermittents
when mouseleave events are somehow simulated in previous tests.
And cleanup the test a little bit so it actually tests something.
