DeferredDelete events not handled when created by GLib dispatched events

Deferred delete events are not handled if they were posted from a glib event callback execution cycle.
loop level for event = loop level for current thread.

I believe the loop level should be incremented before calling g_main_context_iteration in QEventDispatcherGlib::processEvents.

QScopedLoopLevelCounter loopLevelCounter(threadData);

Test App supplied to reproduce the problem.
unzip and ./run
