Specialize MetaObjectForType for non-pointer QObject-derived types
QMetaTypeInterfaceWrapper tries to find the metaObjectFunction using
the MetaObjectForType template. Using SFINAE, for a QObject, it should
resolve to a suitable specialization.
Such a specialization doesn't yet exist. It had to be created.
The following path returns nullptr for registered meta types:
auto metatype = QMetaType(typeId);
requestedTestType.metaObject() -> returns nullptr since a bad template
argument is fed to MetaObjectForType<T> in
QMetaTypeInterfaceWrapper<IneritingFromQObject>::metaType's static initializer.
