title: search JIRA for issues where assignee = reporter
body: <p>I'm trying to do an advanced search in JIRA where the assignee was the reporter.</p>
  
  <p>assignee = reporter doesn't work, it throws this error: 
  The value 'reporter' does not exist for the field 'assignee'.</p>
  
  <p>I'm able to do assignee = currentuser() and reporter = currentuser() without issue but of course that doesn't return what I want.  </p>
