Clear finished jobs' steps a minute after they end

Job steps (bots_queue_updates) only feed the live working row, so the
new clear-job-steps cron deletes them shortly after a job ends, however
it ended, keeping their count on bots_queue.steps for the message
details. Not done the moment a job ends: the live relay would miss the
last ones.
