Issue description

When editing a saved address and switching between two countries with states, e.g. Japan and Hungary an error is shown in the address form.

The provided state (JP02) is not valid. Must be one of: BK, BE, BA, BZ, BU, CS, FE, GS, HB, HE, JN, KE, NO, PE, SO, SZ, TO, VA, VE, ZA
The provided postcode / ZIP is not valid

This shows that server-side validation is still happening against the old country.

Reproduction

0. Disable local pickup (I had trouble reproducing with Local Pickup enabled)
1. Be logged in. *
2. Add an item to your cart and go to the Checkout block.
3. Select Japan as your country. You may use this example address: 2 Chome-19-23 Aobadai, Meguro City, Tokyo 153-0042, Japan
4. Place the order.
5. Add another item to your cart and go to the Checkout block.
6. On the saved address card, edit your address and go immediately to the Country field. Change it to Hungary.
7. Observe the error.

1* This also works if you're logged out, you just have to fill a complete address then change country
