> Global dedup() in reducing by() of group() detaches elements for OLTP

>
> When elements are detached they are not re-attached and thus prevent anything
> following `group()` from traversing them. For example:
> {code}
> g.V().both().
> group().by().by(out().dedup().fold()).
> unfold().
> select(Column.values).
> unfold().
> out()
> {code}
> When {{dedup()}} detaches the later attempt to traverse {{out()}} will
> produce no output as there are no edges on a detached object. I think we need
> to keep detachment in place for OLAP sake where I think this approach was
> envisioned.
