Defect - PostFilter.jsx

[burgwyn]

I believe this is related to #1843

Exception when country is null

  getAllDomesticCodes(props = this.props) {
    return props.item.data.slice().filter(b => b.location.country === 'United States');
  }

  getAllOverseasCodes(props = this.props) {
    return props.item.data.slice().filter(b => b.location.country !== 'United States');
  }
