Event types in the TaskLifeCycleEventListener interface do not match with human task life cycle status

When implementing TaskLifeCycleEventListener interface the following behaviour is  observed: 

1. beforeTaskAddedEvent --> task_status = null
2. afterTaskAddedEvent --> task_status = Ready (or Reserved when autoclaim)

3. beforeTaskActivatedEvent --> task_status = Ready (or Reserved when autoclaim)
4. afterTaskActivatedEvent --> task_status = Ready (or Reserved when autoclaim)

From the above, the task status "Created" is not shown at all. However, the expected behaviour would be: 

1. beforeTaskAddedEvent --> task_status = null
2. afterTaskAddedEvent --> task_status = Created

3. beforeTaskActivatedEvent --> task_status =Created
4. afterTaskActivatedEvent --> task_status = Ready (or Reserved when autoclaim)
