Every address in In-Commerce has "LastUsedAs" status (e.g. last used
billing, last used shipping) for each user. When during a checkout new
address is entered then it is marked with appropriate status.

However marking is done even before address record validation happens
resulting in complete "LastUsedAs" mark reset in case of address validation
error.
