Ecore exe (windows): Fix object destruction/failed creation.

The correct way of disposing of an object in a failed finalisation is to
return NULL, not to delete it.

Also, since the destructor is already called when the object is deleted
anyway, there's no point in having cleanup code in the finalizer too.
