- rename `dossiers_id_with_notifications` to `followed_dossiers_with_notifications`,
- rename `notifications_per_procedure` to `procedures_with_notifications`,
- return an ActiveRecord::Relation instead of the result of the query, so that the call place can compose it,
- `merge` with the wanted Dossier scope in the call places, don’t bother passing it as a parameter,
- use the “state” (now “scope”) parameter as a scope method that can be just applied on `Dossier`.
It is actually the same thing as Gestionnaire.procedures. It already included the procedures with paths as well as the archived procedures, and in production, there were no Gestionnaire for who procedures was returning a different result than visible_procedures (expect for two baddata brouillon procedures with a nil path).
In addition, Procedure.path is now nonnull, which means the Procedure.avec_lien scope is pointless.
Finally, the current spec showed that the only procedure not visible to the gestion was the one he was not assigned to.
