fixed ptrcall cast for const Ref<T>

Some methods require a const Ref<T> argument,
the ptrcall method wrappers cast `void *` to the
apropriate types. The problem is that there is no `Ref(const T *)`
constructor, but since Ref modifies the refcount of a Reference
anyway there's no point in a const version.

The problem is that with a `const T *` constructor call, the
argument gets converted to Variant first and loses all the
reference information, resulting in a null reference as the
argument to the constructor.
