Editing an address answer from the review page collates the answer for city, province and postal code into street address field

## Steps to reproduce
1. Go to a multi-page form with AddressComplete
2. Fill in address using the lookup
3. See the fields auto-populate
4. Continue filling out the form to the review page
5. Change the answers
6. Go back to the address question
7. See how all data is in the first field of the field set

Start by reproducing the multi-page form flow with AddressComplete, including editing the address from the review page. Trace how the address question restores its auto-populated answers when returning to the form. Done means the street address, city, province and postal code remain in their respective fields after editing and navigating back.
