[FIX] website_sale : fix empty result message

before PR:
when searching a product that doesn't exist in the
shop, the error message "no results found for ..."
appears, but when searching another failed product,
we hit the cache and the same "..." is displayed.

after PR:
avoid using the cache for the empty results
message
