Fix PHP 8 compatibility for WCF::handleError()

Quoting from the UPGRADING manual (https://github.com/php/php-src/blob/php-8.0.0alpha1/UPGRADING):

> The @ operator will no longer silence fatal errors (E_ERROR, E_CORE_ERROR,
> E_COMPILE_ERROR, E_USER_ERROR, E_RECOVERABLE_ERROR, E_PARSE). Error handlers
> that expect error_reporting to be 0 when @ is used, should be adjusted to
> use a mask check instead:
