title: GetBlockBlobReference is not working with absolute file path
body: <p>I have stored my file in azure storage and later on trying to read that file using below code. But it is giving an error 404 not found when I am giving the full file path like this 
  "<a href="https://appsdemostore.blob.core.windows.net/content/82b159f4-6730-432d-b061-05cf0cdfa16d.txt" rel="nofollow noreferrer">https://appsdemostore.blob.core.windows.net/content/82b159f4-6730-432d-b061-05cf0cdfa16d.txt</a>". But when I am giving filepath as this "82b159f4-6730-432d-b061-05cf0cdfa16d.txt" it is working.I am facing this issue after upgrading the library.Is there any way to work the code with full fule path. Because in my database they are stored as full file path.</p>
  
  <pre><code>  CloudBlockBlob blockBlob = container.GetBlockBlobReference(filePath);
  
                  return blockBlob.DownloadText();
