Frederik Gladhorn 7f80c96432 Stabilize tst_QApplication::touchEventPropagation 
CI metrics show that this test was flaky ~38 time in 3 days.
The problem is old: after we get a surface, a window manager can still
decide to re-position the window.
The fix is to simply send the touch event in a position where it is sure
to hit the window (usually the offset is the title bar height).

The blacklisting seems to not have worked, I could reproduce the failure
on a linux/xcb machine.
