TINKERPOP-1626: choose() is buggy in OLAP
https://issues.apache.org/jira/browse/TINKERPOP-1626
`ComputerAwareStep.EndStep` was using `path.extend()` and not
`traverser.addLabel()` to append step labels in OLAP and thus, the step label
data wasn't being recorded because `path.extend()` is an immutable operation.
Also, updated `PathRetractionStrategy` to look like `LazyBarrierStrategy's`
recent tweaks to not add a barrier to the end of a traversal -- leave that up
to `RemoteStrategy`.
VOTE +1.

fixed a bug in OLAP ComputerAwareStep.EndStep where labels were not being
appended to the traverser correctly. Also, a small optimization tweak to
PathRetractionStrategy to mirror the barrier-optimization retraction that was
done earlier on tp32/ around LazyBarrierStrategy.
