[FIX] website_sale(_wishlist): adapt tours to delay removal

After the delay removal, those two tours failed for the same
reason. They made a research on the /shop page with a specific
product name, and then opened that product.

With the delay, the page was reloaded with the new search, and we
clicked on the product after the reload.
Without the delay, we directly click on the product (which is in
both case already displayed even before searching), and then the
page is reloaded, so the product is never opened and the tours
fail.

This rev. adapts those tours to either wait for the page to be
reloaded before clicking on the product, or simply remove the
searching step when the requested product is actually the first
one.
