* Handle entries now properly. Omit the binary objectsid and filter s…

…ome elements.

* Breaking change: Change the code which reads the user data!:

            $userData = Yii::$app->ldap->fetchUserData();  // leave as-is!

                $user->email = $userData['mail'];             // instead of $userData['entries']['mail'][0]
                $user->firstname = $userData['givenname'];    // instead of $userData['entries']['givenname'][0]
                $user->lastname = $userData['sn'];            // instead of $userData['entries']['sn'][0]
                $user->phone = $userData['telephonenumber'];  // instead of $userData['entries']['telephonenumber'][0]
