V4: Avoid copying WeakValues with wrapped QObjects
Such WeakValues are kept alive until the respective QObject is deleted.
Therefore they are quite expensive. In this case we don't actually need
a copy as on retrieval we only want a ReturnValue and on inserting we
just want to replace the value in the map.
Fixes: QTBUG-71817
