When there are only few leads, marking a lead as won or lost changes
a lot the won/lost repartition. For onboarding purpose, the cron is launched

When the number of lead in the database reaches the PLS threshold,
the config parameter is set to 0 to avoid the useless check
of the number of lead in the dabase in the future
