Prefill the billing address name only when adding a new address.

Before this patch: "Name required" error in billing address
dropdown opens the address editor and immediately fills out the name
from "Name on card" field, thus confusing the user why the address
editor was opened in the first place.

The fix: Fill in billing address name from "Name on card" only when
adding a new billing address.

After this patch: "Name required" error in billing address
drop down opens the address editor and focuses the empty "Name" field.
