[reg] Remove createIndex method that uses PyObject*

Even though we have support for Void*, having to import
it as an additional class to be able to call a separate
function, is adding too much complexity so something
that should be easy to do, like creating an index
for an itemmodel.

The regression is a change that replaced the way of doing:
    QAbstractItemModel.createIndex(0, 0, PyObject*)
to
    QAbstractItemModel.createIndex(0, 0, VoidPtr(PyObject*))

which is not really intuitive, and is generating other issues.

Included modification in the registries too.
