Generate deterministic fixture for users_select/index_spec
Description
See this comment for context:
One contributing factor to this is that this fixture is very different in CE and EE
This is surprising to me. I thought licensed features were false by default in our spec environment
🤔
Investigation
Since there's some other tests using the old merge_request_for_current_user.html
fixture, it's probably safest to try to add a brand new one just for that part of the view we are interested in.
