Plugin creates issues with caching

Hi team,

Thanks to Charles C, a great researcher from WP Engine – he spotted that your plugin generates a cookie wp_woocommerce_session without any items in the cart on every single page.

This unfortunately invalidates the caching and every page view misses the cache hit due to the cookie suggesting that a user started a session.

Could you please fix your plugin and not generate that cookie unless the user adds something to the cart or logs in? Otherwise your plugin is not usable on large eCommerce websites that require caching.
Thank you
