Fix ordering with simultaneous alerts

Sometimes more than one alert is issued with the same 'sent' date/time. The alert json feed randomly changes the ordering of these alerts in the feed and can result in re-triggering of notifications. The alerts array is now being reverse sorted by 'sent' time and 'id' to keep them consistent when the json feed shuffles them around.
