Add parent tag to QObject.metaObject
Add parent tag to QObject.metaObject

Placeholder until the heuristic for turning unmanaged
pointers returned into children of the method owner is
implemented.

as the QObject is decref'ed by the stack right after the methodName
bound method is put into the stack. (CPython specific)
