A storefront that no longer lists a title still answers a request for it: HTTP 200,
total_results 1, and a product carrying an asin and a few always-returned flags.
Nothing between the request and the file noticed, so a re-download replaced a
metadata file written while the title was still listed - the only copy of that data -
with the placeholder.
Fetch the product before touching the destination, and leave the file alone when the
product carries no title. Reported in issue #1947, where a Canada-only title produced
{"asin":...,"asset_details":[],"is_preview_enabled":false,"is_vvab":false,"rating":{...}}
against every other storefront.
