It breaks when regex type in `consent.disable` exists

[szabogyula]

When you have ['type' => 'regex', 'pattern' => '/.*\.mycompany\.com.*/i'], in consent.disable variable in config breaks the module.

The relevant line:

simplesamlphp-module-consentadmin/src/Controller/ConsentAdmin.php

Line 206 in 799cc20

if (array_key_exists($disable, $all_sp_metadata)) {

There is no type check for $disable variable.

        // Remove services, whitch have consent disabled
        if (isset($idp_metadata['consent.disable'])) {
            foreach ($idp_metadata['consent.disable'] as $disable) {
                if (array_key_exists($disable, $all_sp_metadata)) {
                    unset($all_sp_metadata[$disable]);
                }
            }
        }
