QTestLib: flush DeferredDelete events between every test This makes qtestlib behave more like real Qt applications with an event loop, where exiting the application does indeed flush deleteLaters. And since every test method is supposed to be independent from other test methods, we should even cleanup between tests. For "app less" tests, no flushing happens. Real life use cases: * A unittest for some code (e.g. KIO job) which uses a socket, runs an event loop until the socket communication is done, and ends. However slotDisconnected() does, as recommended, socket->deleteLater(). So the test finishes before the socket has a chance to actually get deleted, and memory leak tools flag a memory leak, which doesn't actually happen outside the unittest. * Deleting a QWebEngineView with deleteLater is even worse than a memleak, it leads to an assert (from a global object destructor) in QtWebEngine if the view deletion hasn't actually been processed.
