Prospective fix to stabilize tst_qwindow::isActive() on Windows 10

Browse Source 
It is conceivable that during the try-compare loop of processing
windowing system events we loose and regain the focus. That would
explain the occasional test failure where instead of the expected 3
focus in events, we have received four.
