Orders created before we introduced slugs don't have a slug. This commit introduces code to work with them. Without these changes, the legacy orders are not reachable any more, and trying to create a link for them, crashes the page. I wrote this commit because in my test environment I had a long-lived order for testing purposes, and the home page crashed because the order would show up in the list of Open Orders.
