issue #4179

COD for FedEx and UPS with customer’s accounts
When a user selects Payment Type COD please remove the UPS/FEDEX/DHL Acc
Number field.

That means that we cannot use customer's accounts for CODs. Also, check
the shipping, even if the customer has a UPS/FEDEX/DHL Acc Number we
need to calculate shipping because we are not going to use their
account.
