Call Taker: "Invoice required" field not rendered properly in Field Trip Details

[landonreed]

The "Invoice required" field always shows "No" regardless of the field value. This looks to be because we're using the wrong field name here:

otp-react-redux/lib/components/admin/field-trip-details.js

Line 165 in 4cf9c0e

<Para>Invoice required: <Val>{invoiceRequired ? 'Yes' : 'No'}</Val></Para>
