Expected Behavior

Calling yield wf.when_all(tasks) on a dynamic list that is empty causes the call to never complete.

Actual Behavior

The call should complete immediately and proceed to next step.

Steps to Reproduce the Problem

if you have a dynamic list of tasks and do yield wf.when_all(tasks) and the tasks array is empty, the call never completes and the workflow just "hangs".
Based on quick code exploration, this issue may be caused by the underlying durabletask-python library.
