"""Sub-query stuff, for things we would otherwise let Eve embed (but don't want to).
Uses app.cache.memoize() to cache the results. However, since this decorator needs
to run in Flask Application context, it is manually applied in setup_app().

Only returns those two fields, so the return value is the same

allowed to cache it globally.
Returns None when the user cannot be found.
