Use reorder instead of reorder!

What does this MR do and why?

Fixes a ActiveRecord::ImmutableRelation error with approvals queries. If suggested_approvers and committers are in the same query GraphQL will throw a ActiveRecord::ImmutableRelation because the committers query has been loaded and memoized. Run the below query to see this happening:

query {
  project(fullPath:"gitlab-org/gitlab") {
    mergeRequest(iid:"104092") {
      approvalState {
        suggestedApprovers {
          nodes {
            id
          }
        }
      }
      committers {
        nodes {
          id
        }
      }
    }
  }
}
