Use isset() to avoid warning

PHP Warning:  Undefined property: Dxw\DxwSecurity2017\Lib\PluginVersionChecker::$slug in /var/www/html/wp-content/themes/dxw-security-2017/app/Lib/PluginVersionChecker.php on line 98

I think the code I've pushed here makes sense, but I can't replicate the warning with curl -I http://localhost/wp-json/v1/inspections/flibble

Also this branch will need to be rebased if we want to merge this
