ServiceAPI: Cannot add organization as duplicated AddressId

Description

Steps to reproduce

1. Run POST /episerverapi/commerce/customers/organization/ with attached data (no AddressId)
2. Run about request one more time without changes.

Expected:
You can post another organization with same info in step 1. (After step 1, an address is created with a random guid for AddressId.)

Actual:
After step 1, an address is created with AddressId is " (00000000-0000-0000-0000-000000000000)." So you cannot post an organization with
"ExceptionMessage": "Violation of PRIMARY KEY constraint 'PK_cls_Addr_091C2AFBD96D595D'. Cannot insert duplicate key in object 'dbo.cls_Address'. The duplicate key value is (00000000-0000-0000-0000-000000000000).\r\n The statement has been terminated.",
