[Reg 6.4->6.5] Assertion when referring to C++ methods

The attached example asserts in

qtdeclarative/src/qml/jsruntime/qv4qobjectwrapper_p.h, line 99

for 6.5 branch, but works for 6.4.1. The example itself doesn't make much sense, as it was removed from it's original context, but it creates the same issue.

It works for non C++ methods.
