Uncaught Error: get_check_vulnerabilities()

Hello,

I’m running version 1.15.2 of the plugin and keep getting the following error:

[14-Jun-2021 11:05:32 Europe/London] PHP Fatal error:  Uncaught Error: Call to undefined method WPScan\Checks\System::get_check_vulnerabilities() in /opt/bitnami/apps/wordpress/htdocs/wp-content/plugins/wpscan/app/Summary.php:188

I checked and get_check_vulnerabilities() does not exist in the referenced class. Swapping it to security_check_now() seems to resolve the issue.
