title: from ext_localconf.php eID called controller makeInstance does not find any Repository
body: <p>Because of using ajax i have a eID configured, see below:
  I would like to use a existing repository of my extension. So i'm loading a Controller via ext_localconf.php which works, i'm in the TestController:</p>
  
  <pre><code>$TYPO3_CONF_VARS['FE']['eID_include']['ajaxDispatcher'] = \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::extPath('exacallmanagement').'Classes/Controller/TestController.php';
  </code></pre>
  
  <p>In TestController i run:</p>
  
  <pre><code>\TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('VENDOR\Exacallmanagement\Classes\Domain\Repository\CallhistoryRepository');
  </code></pre>
  
  <p>Namespace should be correct, and i always get a:
  Fatal error: Class '\VENDOR\Exacallmanagement\Classes\Domain\Repository\CallhistoryRepository' not found in /Users/jacques/Sites/_typo3_engines/6.1.6/typo3/sysext/core/Classes/Utility/GeneralUtility.php on line 4114</p>
  
  <p>Any hint?</p>
