Cron: execute rules ordered by rule_id
Currently CRM_Civirules_BAO_Rule::findRulesForCron()
returns rules unordored so the order in rules are executed by cron is undefined.
Changing this to an ordered list has these pros:
- rules are executed consistently each day
- debugging is easier: just by looking at Last Triggered you can determine which rules succeeded/failed
Cons: ???
