title: Ms Graph http call to get profile picture/photo is slow when user has no picture/photo
body: <p>When I try to get the profile photo of a user which has no photo it takes 4s - 8s  in average until I get a 404 error. </p>
  
  <p>When the user has a photo the response time is much faster. Is this something general or is this maybe a problem in our environment?</p>
  
  <p>You can easily reproduce this by using <a href="https://developer.microsoft.com/en-us/graph/graph-explorer" rel="nofollow noreferrer">Graph Explorer</a> and with a call to a user which has no photo:</p>
  
  <pre><code>https://graph.microsoft.com/v1.0/users/{userid}/photo/$value
  </code></pre>
  
  <p>Edit: Found that is slow for users which have no licence. But this should still not take 4s-8s.</p>
