Make sure profile fields exist before attempting to set default value

We should check that the entity has fields (ie: commerce_customer_shipping) before attempting to set their value in commerce_addressbook_commerce_order_insert(). Even though, order bundles aren't recommended in the current version of commerce, this module dies fatally when using them because of this bug.

Here's a patch does the check using the wrappers getPropertyInfo() method. We could use field_info_instance or something else if that's preferred, but this works for me.
