This avoids an unnecessary join to UserProfile.
To verify this, you can do `print(queries)` in the
`test_get_custom_profile_fields_from_api` test. It's
kinda noisy, so I excerpted them below...
Before:
SELECT ...
FROM "zerver_customprofilefieldvalue"
INNER JOIN "zerver_userprofile" ON ("zerver_customprofilefieldvalue"."user_profile_id" = "zerver_userprofile"."id")
INNER JOIN "zerver_customprofilefield" ON ("zerver_customprofilefieldvalue"."field_id" = "zerver_customprofilefield"."id")
WHERE "zerver_userprofile"."realm_id" = 2
After:
SELECT ...
FROM "zerver_customprofilefieldvalue"
INNER JOIN "zerver_customprofilefield" ON ("zerver_customprofilefieldvalue"."field_id" = "zerver_customprofilefield"."id")
WHERE "zerver_customprofilefield"."realm_id" = 2'
I don't have any way to measure the two queries with
realistic data, but I would assume the second
query is significantly faster on most of our instances,
since CustomProfileField should be tiny.
