Notice about CRM_Aivlspecificactions_ExtensionUtil

I noticed a notice that was hardly noticable:

Error: Class 'CRM_Aivlspecificactions_ExtensionUtil' not found in Civi\Emailapi\CompilerPass->process() (line 19 of /var/www/vhosts/xyz/webroot/sites/all/modules/civicrm_extensions/emailapi/Civi/Emailapi/CompilerPass.php).
