TINKERPOP-1947 Fixed path history problem with mutations
https://issues.apache.org/jira/browse/TINKERPOP-1947
When a key of a mutation was a traversal it was not being integrated to the
parent traversal and tracked in the Parameters. Works now with:
```text
gremlin>
g.withSideEffect('k','name').addV('person').property(select('k'),'stephen')
==>v[3]
```
All tests pass with `docker/build.sh -t -n -i`
