When including multiple autoload.php files during the same runtime, Composer InstalledVersions relies on the registered autoloaders to be able to resolve all available packages. If class alias loader is now calling ->unregister API, the static registry of available classes is removed, which does not reflect the state when class alias loader is registered. Therefore, we now call spl_autoload_unregister ourselves instead of using the API, because the classes will be loadable, just not directly but proxied through class alias loader
