fix: Handle region updates on cart (1/n) (#9369)

Browse Source 
**What**

On cart creation:
- If region only has one country -> create cart with country code

On cart updates:
- If shipping address country code is provided in input ->
  - If cart region doesn't include that country -> throw
  - If cart includes the country -> update shipping address
- If region is provided in input and is different from the one currently on the cart -> 
  - If there is a shipping address on the cart -> clear the address
    - If the region only has one country -> set country code of address
  - If there is not a shipping address on the cart ->
    - If the region only has one country -> set country code of address
