@drcrallen adding test looks tricky. I can try if you really want. |

Fix state check when a replacement task is started in place of a failed task. Without this fix, service can get into state where tasks are continuously failing and Supervisor is continuously starting new replacement tasks.
The problem is that if any task has done some handoffs then the start offsets of the latest sequence will not match with the start offsets of the task group, thus in the replacement task the condition check will fail.
