Customer - E-mail Address Billing rather than Contact

It appears that only the billing email address is returned for customers. Usually, the contact e-mail would default to the billing e-mail when an order is placed, but it is possible that the customer wants a different billing email address to their contact email.

This user Test has just been set up without paying and without a billing address

In Woobase - no email address is returned

Changing the defaulted billing e-mail to a different address

In Woobase the billing email address is returned (and strangely Text format and Avatar changed from the non paying customer default)
