[site-reviews] disable the nonce check

/**
 * This removes the nonce check for logged-in users when submitting a review.
 *
 * A nonce is a special generated security token that expires after 12 hours.
 * Nonces prevent malicious form submissions and is an additional security measure
 * used in WordPress forms for logged in users. Nonces can be problematic when your
 * pages are cached. It's general practice in WordPress to not cache pages for
 * logged in users for this reason. However, if caching is required on your site
 * for logged in users, then this snippet will disable the use Site Reviews nonce
 * check for submitted reviews.
 *
 * @see http://developer.wordpress.org/plugins/security/nonces/
