Bug 1990127: Adjust reftest 593243-2.html to wait on MozReftestInvalidate to detect when initial painting is done (rather than MozAfterPaint). r=tnikkel,layout-reviewers

MozAfterPaint may fire very early, before the load event has even fired, so it's
not what this test really wanted to be using.

Note also that MozReftestInvalidate only fires once, so we don't need to bother
unregistering the event listener inside of 'initialPaint' anymore.
