TINKERPOP-1547: Two bugs found associated with MatchStep: Path retraction
and range count.
https://issues.apache.org/jira/browse/TINKERPOP-1547
Two bugs had always existed because we had commented out tests due to their
failure. Fixed the bugs and exposed more tests. Also, some `match()` benchmarks
got faster. Finally, I found a bug in `MatchStep.clone()` that only makes
itself apparent (and randomly) when there is a `match()`-step within a local
child of an OLAP traversal with single processor threading.
VOTE +1.

fixed a bug in MatchStep that I forgot we had. Because of it, we had 3
tests commented out. Doh. The tests were a combination of problems in
PathRetractionsStrategy and RangeByIsCountStratyegy. Because of the fix in
PathRetractionStrategy, some match benchmarks got significantly faster.

updated CHANGELOG and fixed a MatchStep.clone() bug that exposes itself in
OLAP traversals with OLTP match() children.

> {{PathRetractionStrategy}} can retract end labels from traversals and thus,
> ruin a pattern match. We had 3 traversals in our test suite that were buggy
> because of this. Finally, if the user does a pattern of
> {{as("a").count().is(gt(10)).as("b")}}, this will fail because of
> {{RangeIsCountByStrategy}}.
