JOC Dashboard: Click on healthy agent clusters shows an empty list

Current Situation

JOC shows a widget in the dashboard that informs about the number of healthy agent clusters. When clicking an item, an empty list is shown. The reason for this is a wrong post body

{"jobschedulerId":"scheduler_joc_cockpit","state":0,"folders":[{"folder":"/","recursive":false}]}

Desired behaviour

JOC shows a widget in the dashboard that informs about the number of healthy agent clusters. When clicking an item, the resulting list list should be shown. To achieve this the post body should be

{"jobschedulerId":"scheduler_joc_cockpit","state":0,"folders":[{"folder":"/","recursive":true}]}
