I've merged this branch into `master/` (locally), but it didn't change
anything (which is actually a good thing, as I don't like surprises after a
merge :)). We still get the kinda unexpected empty list in OLTP and the whole
bunch of empty lists in OLAP:
```
gremlin> g =
TinkerFactory.createModern().traversal().withoutStrategies(StandardVerificationStrategy)
==>graphtraversalsource[tinkergraph[vertices:6 edges:6], standard]
gremlin>
g.V(1).repeat(aggregate("a").fold().store("x").unfold().both().where(without("a")).dedup()).cap("x").next()
==>[]
==>[v[1]]
==>[v[3],v[2],v[4]]
==>[v[6],v[5]]
gremlin> g =
TinkerFactory.createModern().traversal().withComputer().withoutStrategies(StandardVerificationStrategy)
==>graphtraversalsource[tinkergraph[vertices:6 edges:6], graphcomputer]
gremlin>
g.V(1).repeat(aggregate("a").fold().store("x").unfold().both().where(without("a")).dedup()).cap("x").next()
==>[v[1]]
==>[]
==>[]
==>[]
==>[]
==>[]
==>[v[2],v[4],v[3]]
==>[v[5],v[6]]
```
The results are the same in `tp32/` and `master/`, nothing's changed.
So, although the issue looks similar, it's probably a whole different thing
that just happens to produce the same kind of unexpected result entries.
