FIx password setup for email loging

 By default the  all repositories/clients get user  as role_id on the welcome event  https://github.com/datacite/lupo/blob/d219ea02ba99f11b54e41a4a776ada1c0d37e5fc/app/models/concerns/mailable.rb#L20 .
But now in Fabrica, I think this role_id is now  used exclusively by researchers in fabrica datacite/bracco@b34d86b#diff-02dddb4b8cfd2bf611557d5902eb96a2 .
So then the Fabrica app in production gets into a error loop
