Fix tst_gestures flakiness on XCB

Browse Source 
X11 spawns painting threads and sends an expose event at the same time.
While the worker is still paining, QXcbScreen::topLevelAt() may not
find the window, even if it reports being exposed.

Wait until windows are exposed and painted.
Remove workaround to intercept warnings about undeliverable gestures.
Remove qWait() antipattern.
