Remove search query from url bar on empty query
Remove search query from url bar on empty query

When emptying the search query box, we don't trigger the change to the
query in the URL bar, resulting in a value being stored in the URL
without a corresponding search in the box. To fix this, we simply delete
the search__search key when the search box is empty.
