Michal Klocek b1e3f33a28 Call post routines from ~QGuiApplication
Currently depending if user uses QApplication
or QGuiApplication we end up in different behavior
when running post routines. For example QApplication
destructor calls post routines before stopping event dispatcher,
In case of QGuiApplication post routines are called
from QCoreApplication destructor, so no more event dispatcher.
This behavior is not consistent and creates troubles
when releasing resources of web engine.

Attached test will hang on windows with QGuiApplication,
however works fine with QApplication.
