when in StartNextGroupRolloutGroupSuccessAction#startNextGroup:
1. start all scheduled actions
2. if started are > 0 -> RUNNING, otherwise -> FINISHED (if not dynamic rollout)
what could possibly happen is that at same time:
* because of a success condition met the JpaRolloutsExecutor triggers start the group
* user triggers start of the next group (via RolloutsManagement#triggerNextGroup)
then it could:
* the 'first' one succeeds to start next group
* the second attempts to start it (JpaRolloutsExecutor found the previous had met the success condition or trigger next found it SCHEDULED and next to run)
* the second finds no scheduled actions (just running) and decides there are no actions. So, it assumes (wrongly) no actions in group - and set it as FINISHED
This way we could have FINISHED group with still running actions
