Add MembersPreloader to fix ActiveRecord copce-jej/group-saml-sso-badges

MembersPresentation was previously preloading records and we wanted to
extend this in
https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/5807

By moving this to MembersPreloader we avoid introducing a new cop
exception that would otherwise have been needed
in EE::MembersPresentation
