Tests: stabilize tst_QAbstractScrollArea::setScrollBars2()

Use QWidget::isVisibleTo(parent) instead of isVisible(), just like
QAbstractScrollArea::replaceScrollBar() does. This removes the need
of using QCoreApplication::processEvents() to deliver the actual
hide event just for testing if the scrollbar was requested to be
hidden as it should.
