Title: Don't update shipping addr if use billing addr is checked

By running updateState() on shipping address form we enable those
fields and need to propagate changes from billing address to shipping
address when we shouldn't because they're already propagated server
side. We should only run updateState() on shipping form if use billing
address is not checked

Fixes #3232

2-0-stable needs this fix as well in case it's merged
