Incomplete next staged concurrent task with items if last running nested item fails.

[eg-lom]

The below workflow didn't execute Nested6 for subsequent items in listed, if it fails for any item in listed. Basically if last running concurrent nested task is failed than it marks the staged task as completed and didn't pick the next task from staged items.

I have proposed a change which worked for me in a PR #221. Where I have update the TASK_STATE_MACHINE_DATA map for current state to new state for event events.ACTION_FAILED_TASK_DORMANT_ITEMS_INCOMPLETE: statuses.RUNNING.
