Tried calling this method (descend_by_popularity) for Spree::Product in console and got the error: `disallow_raw_sql!': Query method called with non-attribute argument(s)

Perhaps this scope is not used very often, I couldn't find a reference to it anywhere else in the repo or in either solidus_starter_frontend or solidus_frontend.

Anyway, it appears to be a quick fix, just need to add Arel.sql, will submit a pull request.
