Fix assertion at shutdown or on QObject destruction.

When handling the destroyed signal of a QObject, the QMetaObject of the
sender() will point to the global static QObject meta object. Thus, we
also cache its signal argument types. This way, we are able to properly
handle the destroyed signal with minimum effort.
