Fix MR assignees for push options

Closes #60305

See merge request gitlab-org/gitlab-ce!27186

With multiple MR assignees, `merge_request.assignee_id` is always nil,
and `merge_request.assignee_ids` isn't in `merge_request.attributes`.
So the existing code doesn't set assignees in the created MR.

This fix gets all the tests passing, but we should also check that no
other associations in the MergeRequest need similar fixups.
