This PR fixes a TypeError when trying to look up an attribute for a collection type caused by the class missing a
__hash__
definition. This was causing some models to fail to load. I also added two tests, one to test a passing example of aattrname
lookup, and a 2nd that was failing with a collection object and is now passing.PR Checklist
