The `users_select_tag` helper defaults to using `@project`, which in this case
is the source project, not the target project. Explicitly use the target project
to get the right list of users.

1. Use the ProjectAuthorization model to find users with developer access to
   this project. This is dramatically faster than the old version, with the
   complicated ORs, on staging: ~10ms vs ~800ms.
2. Use `to_a` explicitly when checking `any?` on a relation. Refactoring out the
   `any?` checks would be painful, but as we often use the results anyway,
   `to_a` lets us save a query.

Adding this up gets us the below (for a MR on the gitlab-ce project in staging).
