Set shipping and billing address when loading a customer in order creation

In the order creation, when customer details view is opened:

1. We make a call to wc-analytics/customers to fetch customers who made past orders
2. WCAnalyticsCustomer is mapped to Storage.Customer, however, we don't map all the available data in the WCAnalyticsCustomer, making shipping details get lost
