title: DurableOrchestrationClient.GetStatusAsync() always null for Durable Azure Function
body: <p>I have a queue trigger azure function with DurableOrchestrationClient.  I am able to start a new execution of my orchestration function, which triggers multiple activitytrigger functions and waits for them all to process. Everything works great.  </p>
  
  <p>My issue is that I am unable to check on the status of my orchestration function("TestFunction").  GetStatusAsync always returns as null. I need to know when the orchestration function is actually complete and process the return object (bool).  </p>
  
  <pre><code>public static async void Run([QueueTrigger("photostodownload", Connection = "QueueStorage")]PhotoInfo photoInfo, [OrchestrationClient]DurableOrchestrationClient starter, TraceWriter log)
  {
       var x = await starter.StartNewAsync("TestFunction", photoInfo);
       Thread.Sleep(2 * 1000);
       var y = await starter.GetStatusAsync(x);
  }
  </code></pre>
