title: System User not getting manage_pages permission from page access token
body: <p>I made a system user and he has permissions of manage_pages.</p>
  
  <p>Then from his access token I made a call to this URL</p>
  
  <pre><code>me/accounts
  </code></pre>
  
  <p>Then the pages were listed below with their access tokens.</p>
  
  <p>Then those access tokens didn't have manage_pages permission.</p>
  
  <p>Problem:
  I need manage_pages permission on those page access tokens.</p>
