title: integrate Jira with existing app with webhooks - no email sent to the customer if agent replies
body: <p>I have an app and I wanna integrate my Jira desk instance with it!</p>
  <p>I've started to create two webhooks in the Jira desk:</p>
  <ol>
  <li>new customer creation (create new customer from email)</li>
  <li>create a new issue for the user (from the email of user created before, the customer is a reporter)</li>
  </ol>
  <p>everything works like a charm and I love it.</p>
  <p>but there's a problem! no email is sent to a customer if an agent reply to his issue!</p>
  <p>in notification helper:</p>
  <p>V    USERXXX receives notifications for the 'Issue Commented' event</p>
  <p>X    USERXXX does not get notified of its own changes.</p>
  <p>seems that notifications are enabled for the new customer but no mail arrives! any help?</p>
