Set primary account address as the default

The shipping select no longer defaults to the primary account as
orderFulfillment.getShippingAddress() is no longer null with recent
changes. This checks to see if the addressID returned is an empty string
and if so, sets the accountAddressID to be the account primary
addressID.
Instead of these two conditions, can you just change it to say:

<cfelseif orderFulfillment.getShippingAddress().getNewFlag() && not orderFulfillment.getShippingAddress().hasErrors()>

You may want to test that... but if you enter a "New" address and it has errors I think this code would go back and auto-select the accountAddressID again.
