Visiting /search causes error

[mehrdad-shokri]

What I'm trying to achieve

I'm trying to open /search on saleor storefront. I expect to see usual search box on this page to search my things but it causes error(which shows to user) by sending empty request to backend.
…

Steps to reproduce the problem

1. visit https://demo.saleor.io/search/

What I expected to happen

…
I expect (as a user) to not cause any error by visiting any page. I expect to not send any http reqeust when my search input is empty. Also, I expect the usual search box to initiate a search.
