The catalyst-daily-* jobs can fail when the teardown publisher's castor-save trigger fails to start its downstream job on the castor node, even though Selenium passed and the environment was torn down cleanly. castor-save is a no-op on the daily pipeline anyway, so drop it and use docker-cleanup instead.
see https://integration.wikimedia.org/ci/view/selenium-daily/job/catalyst-daily-Newsletter/7/console or P94808 for an example of this failure
