iterclass added uri_tags and uris and removed sorting from __iter__
iterclass added uri_tags and uris and removed sorting from __iter__

Some children of HypothesisHelper have very expensive calls to __gt__
so we no longer sort by default.

Fixed a bug where we were checking against text and tags instead
of updated to see if an annotation had changed value.

Added simple uri normalizeation to byIri until refactor to use
uri_normalized throughout the codebases that use this.
