narrow: don't do the dirstate dance if ellipses is not enabled

I believe we set dirstate parents to nullid before widening pull because in
ellipses cases, the parent might be stripped off with a new changeset. However
the second ds.setparents() call invalidate my assumption. I am not sure why we
do this. So here is a patch.

This patch also adds tests showing we break nothing in non-ellipses cases.
