To confirm that QueryRecorder works

What does this MR do and why?

This MR introduces N+1 to confirm that QueryRecorder works as expected. CI should fail for bin/rspec spec/requests/api/members_spec.rb. For some reasons the following specs do not fail on my environment:

API::Members
  behaves like GET /:source_type/:id/members/(all)
    with :source_type == projects
      avoids N+1 queries
  behaves like GET /:source_type/:id/members/(all)
    with :source_type == groups
      avoids N+1 queries
