fix(py3): Fix tests in test_organization_group_index (#20848)

This fixes tests in tests/snuba/api/endpoints/test_organization_group_index.py. Problems:
 - Treating the result of `range` like a list. Just casted as a list. I also searched for other uses
   of this in the codebase and fixed.
 - Needed to encode the result of a repr before passing to md5. Also converted from repr to
   json.dumps. I don't think that the hash is important here, so it's fine for it to change.
