[tauruslib-devel] [PATCH 3/3] Fix bug#226 EvaluationAttributeNameValidator.getUriGroups fails

[cfalcon <cf...@ce...>]

EvaluationAttributeNameValidator.getUriGroups for modern Uris without
substitutions returns the group '_subst' as an empty string
instead of None.

Modify EvaluationAttributeNameValidator.path attribute to fix the bug.
