Acho que devemos tratar as exceções `Webpush::InvalidSubscription` e `Webpush::Unauthorized` cancelando a inscrição. Parece que elas não existiam quando atualizamos pela última vez o [tratamento de erros](https://github.com/discourse/discourse/blob/eb25d3a954d03792bce29cda01420807842df25f/app/services/push_notification_pusher.rb#L102-L118) para notificações push.
