This PR will:

• assert if a customers default address is valid within a given address identifier (We only have one default address, but multiple types of address identifier).
• check if valid shipping addresses are available in address checkout step. if not, disable useInvoiceAsShipping checkbox since it is not possible to use it
• add validation groups to the NotBlank constraints
• Improve UI in address checkout step: if shippingAddress is not valid, show selector after page reloads.
• If useInvoiceAsShipping has been checked, check if invoiceAddress can be assigned to shippingAddress first - if not, throw a proper exception. To be clear: This is just a development improvement to speed up the issue tracking time. The check itself should be done after a user selects an address (by JS for example).

Also wrong, needs to be checked if invoiceAddress can be assigned to shippingAddress first!
