scoper-autoload.php doesn't support PHP 5.6 (again)

This is a followup to #842. I found another thing in `scoper-autoload.php` that is incompatible with PHP 5.6 - the `??` operator. PR incoming.

See the error here: https://github.com/skaut/skaut-google-drive-gallery/actions/runs/8883783876/job/24391429247?pr=2632
