Ensure that posted events are sent by Q*Application::processEvents()

Commit b7ca6a81dbf6a2b96c8f04b856372050618e60c0 removed a call to
sendPostedEvents() that deemed unnecessary. Unfortunately, it is
necessary, as shown by the
tst_QScriptEngine::processEventsWhileRunning() test in the QtScript
module. Re-add the call, but only when not waiting for more events.
