Heads up that task.delay() returns None, not AsyncResult.

[fladi]

The original Task from celery returns an AsyncResult for task.delay() and task.apply_async(args, kwargs). I think it should be mentioned that this package exhibits a different behavior (due to technical limitations) and how to work around this in order to track tasks later on.
