Title: Change product_url to product_path.

I'm not sure why product_url was introduced, but I'm currently
encountering issues in production where it's not respecting subdomains,
HTTPS, and ports correctly.

Nearly everything else in Spree links to stuff using the _path helpers,
which I like a lot better.
