Carbon: QApplication auto test shows bug in event dispatcher

The reason for the bug is that we call _quit_ on the eventloop
just _after_ posting the deffered delete event (from inside
deleteLater function, ref the test where it fails,
tst_qapplication.cpp:1242). And the point is, even if the loop
level tells us that we _can_ delete the object in this case, the
'quit' tells us that we should not process _any_ events (until we
get a call to processEvents again).
So this patch makes sure that we don't call sendPostedEvents from
the eventDispatcher if it is interruped.
