Previously it could be set by any call to the `set_state_in_scheduler`
method.
This was leading to side effects on the save bulk lister while updating
the scheduler state when encountering an invalid or not found origin,
and thus the listing failed.
Fixes#4712.
It enables to track last lister execution date and will be used to schedule
first visits with high priority for listed origins.
Related to swh/devel/swh-scheduler#4687.
Ensure that all lister classes have the same set of mandatory parameters
in their constructors, notably: scheduler, url, instance and credentials.
Add a new test checking listers classes have mandatory parameters declared
in their constructors. The purpose is to avoid deployment issues on staging
or production environment as celery tasks can fail to be executed if mandatory
parameters are not handled by listers.
Reated to swh/infra/sysadm-environment#5030.
