Replace name_on_certificates property with name_on_documents, since mentors, club admins, hosts and org admins don't get certificates it's better to name it 'Name on documents' which can indicate any kind of documents including awards certificates. Also don't show name_on_documents in public Role profiles, instead show user public name in that place. Patch by: Pawel Solyga Reviewed by: to-be-reviewed
