[FIX] website_sale: remove click from tour when checking button

This step was meant to be "check" but did "click" instead because no empty
function was provided.

This caused a nondeterministic issues where an unwanted RPC generated a warning.
Indeed by clicking "add to cart" when checking if the button is disabled, that
called `create_product_variant` on non-dynamic product.
