Title: Clean up after track selection experiment

This cleans up the code left over from the track selection experiment ([ECOM-16](https://openedx.atlassian.net/browse/ECOM-16)). These changes don't include cleanup of the SCSS used to style the `choose`, `_verification_header`, and `_verification_support` templates; that seemed like a separate story, and UX is out today.

@wedaly and @stephensanchez, could you review this?
