Stabilize tst_qgraphicsitem and tst_qgraphicsview

Browse Source 
Add qWaitForWindowExposed() calls in addition to the
existing qWaitForWindowActive().

Depending on the platform, window activation events may
be synchronous, which means that a window can (and will)
become active before it becomes exposed.

This causes test failures for tests that count paint
event, and does not wait-for-exposed, when the expose/paint
event is delivered after waitForWindowActive() has returned.

We need to keep the waitForWindowActive() as well: the
test has several qWait() calls with he comment:
  “Increase the probability of window activation not
   causing another repaint of test items”.
These qWait() calls can possibly be removed in a future
commit.
