Content pages with columns are not upgraded properly from 7.2 -> 7.3. The responsive column settings are not respected.

Steps:

1. Start a 7.2 portal
2. Add a content page
3. Add a Layout element to page with three columns
4. Add a card fragment to each column
5. Publish the page
6. View the page at a mobile breakpoint - each column takes full width
7. Shutdown the server
8. Upgrade to 7.3
9. Navigate to the page and view in a mobile breakpoint

Expected Result:

Each column takes full width

Actual result:

Each column takes up 1/3 of the viewport width
