I've seen lots of code where people actually use `id` as a property name.
```
gremlin> g = TinkerGraph.open().traversal()
==>graphtraversalsource[tinkergraph[vertices:0 edges:0], standard]
gremlin> g.addV().property("id", UUID.randomUUID())
==>v[0]
gremlin> g.V().valueMap(true)
==>[id:0,id:[02f29cc6-7f04-477c-a884-d5196064109a],label:vertex]
gremlin> g.V().project("vertexId","applicationId").by(id).by("id").next()
==>vertexId=0
==>applicationId=02f29cc6-7f04-477c-a884-d5196064109a
```
Those people would be in big trouble if we would merge this PR:

> PropertyMapStep returns Map<String,E> but puts non String keys in it!

> Issue Type: Bug
> Components: process
> Affects Versions: 3.2.2
> Reporter: JP Moresmau
>
> PropertyMapStep.map has return type Map<String,E>, but if includeTokens is
> true:
> {code}
> if (element instanceof VertexProperty) {
> map.put(T.id, element.id());
> map.put(T.key, ((VertexProperty) element).key());
> map.put(T.value, ((VertexProperty) element).value());
> } else {
> map.put(T.id, element.id());
> map.put(T.label, element.label());
> }
> {code}
> T.id, T.key and T.value are NOT strings, so code looping through the keys in
> Java fails. toString() are missing... But do we rely on having these keys in
> other operations?
