Eike Ziller 711ac6602f Fix C++ type hierarchy
Dynamic casts between library boundaries tend to fail. Add an "explicit
cast" to CppClass via virtual functions as a quickfix.
This is a recurring issue, e.g. d2769f3003, 3f11ef9216 and
2ffd0e2d0d to name just a few...

This was introduced in 5e861d2be6

Task-number: QTCREATORBUG-20001
