Adjust default of countries lived in + dates in combined questions

[mnewsted]

In combined_application_questions.yml, on id: status in other countries, I think the default here needs to be ${ showifdef("users[0].lived_in_countries_traveled_through_dates") if i > 0 else '' } With the current code (below) it's defaulting to "True". Here's the full field:

  - Which country, and what dates did you live there?: users[i].lived_in_countries_traveled_through_dates
    datatype: area
    show if: users[i].lived_in_countries_traveled_through
    default: |
      ${ showifdef("users[0].lived_in_countries_traveled_through") if i > 0 else '' }

Other minor tweaks: Remove footer since not used in this scenario Adjust I-821 - Part 2, question 5 - make checkbox style cross to be consistent with other fields
