> Instead of throwing an exception, we should stop traversal if a {{by}} clause fails to produce.
> Current:
> {noformat}
> gremlin> g.V().as('a').out().out().as('b')
>   .select('a', 'b')
>   .by('name')
>   .by(has('name', 'lop').values('name'))
> The provided start does not map to a value: v[5]->[HasStep([name.eq(lop)])]
> {noformat}
> Desired:
> {noformat}
> gremlin> g.V().as('a').out().out().as('b')
>   .select('a', 'b')
>   .by('name')
>   .by(has('name', 'lop').values('name'))
> ==>[a:marko, b:lop]
> {noformat}
