Manipulating NULL iterator should be concidered as a defined behaviour as it 

give the possibility to write small code like :

it = eina_hash_iterator_tuple_new(hash);
eina_iterator_foreach(it, do_something_cb, NULL);
eina_iterator_free(it);

If hash is empty, but valid it will return a NULL iterator for this
example.
