title: Can't login via Facebook iOS SDK 3 with a test user
body: <p>Have a code that is working with ordinary FB user (login and post). Just created test user but unable to login. Getting message "we didn't recognize your email address or phone number". After calling <a href="https://graph.facebook.com/362652477144946/accounts/test-users" rel="nofollow">https://graph.facebook.com/362652477144946/accounts/test-users</a>?... I got:</p>
  
  <pre><code>{
    "id": "100004233554579",
    "access_token": "...",
    "login_url": "https://www.facebook.com/platform/test_account_login.php?user_id=100004233554579&amp;n=Ffaa4FVusNloYGS",
    "email": "iosproject_gaxfjez_iosproject\u0040tfbnw.net",
    "password": "..."
  }
  </code></pre>
  
  <p>Tried entering "100004233554579", "Ffaa4FVusNloYGS" and "iosproject_gaxfjez_iosproject\u0040tfbnw.net" at username but nothing works. Any ideas?</p>
  
  <p><strong>UPDATE1</strong> Noticed "\u0040" in email, so changed that to "@". But then getting "We didn't recognize your email" :)</p>
  
  <p><strong>UPDATE2</strong> Noticed there's another email "100004233554579@facebook.com" when logged to Facebook login_url but it doesn't work too.</p>
