title: New code not showing up in sonarqube code coverage measures
body: <p>New code (I've checked and it's definitely new) doesn't always show up under code coverage measures.</p>
  
  <p>I see no link saying 'On New Code X.Y%'</p>
  
  <p>Interestingly, I do get an 'On New Code X.Y%' link in the maintainability rating.</p>
  
  <p>Is there a good reason for this?  If it's a bug, it's happening on other projects too, and seems to occur quite commonly.</p>
  
  <p>I'm running Sonarqube 5.6.5</p>
