Testing story

Validated all pages sort as expected during "post-hoc" mode. During "pre-hoc" mode only code.org/learn will sort by popularity as was the behavior previously.

Reviewer Checklist:

• Tests provide adequate coverage
• Code is well-commented
• New features are translatable or updates will not break translations
• Relevant documentation has been added or updated
• User impact is well-understood and desirable
• Pull Request is labeled appropriately
• Follow-up work items (including potential tech debt) are tracked and linked

This logic for the sort order is starting to get a little complex! And it's duplicated between the code.org and hourofcode.com helpers. Let's extract it someplace and write tests for it.

I think this is a good candidate for a class method on the Tutorials class in database.rb. There are already some tests for that class. Maybe a signature that looks like this?

def self.sort_by_popularity?(site, hoc_mode)

Let me know if you'd like to chat about this in person.
