Pivoting a TraversalURIOptimisedQuery is broken in release 1.13.2

- fix query building for TraversalURIOptimizedQuery
- enable DataLinkTests for TRAVERSAL_URI again
- add further tests to test pivoting more directly
- roll back version to 1.13.2 to rerelease fixed version
- add python six dependency to fix upstream issue with sphinxcontrib-swagger dependency
