Oops, fix error in modeling query on homepage

Okay, legit, I'm reading over this and I don't understand why `item_id`
isn't working here? It seems like we have `SELECT DISTINCT items.id AS
item_id`, and we use it in the `ORDER BY` clause right below. And I
don't see why, presumably, it's our item translations changes that
broke this?

But in any case, okay! This fixes it! Moving on!
