Bad VAT calculation in mixed scenarios

[Hlavtox]

In certain scenarios, the VAT calculation is wrong.

Scenario 1

• You are a French shop.
• Tax address in Prestashop is set to invoice address.
• You go to checkout:
• Invoice address - German customer, valid VAT number
• Delivery address - French customer, regular.
• Result - 0 % VAT 🔴
• Expected - normal VAT.
• Reason - the module receives only one address, it needs both to resolve the proper VAT.

Scenario 2

• You are a French shop.
• Tax address in Prestashop is set to delivery address.
• You go to checkout:
• Invoice address - German customer, valid VAT number
• Delivery address - German customer, regular.
• Result - normal VAT 🔴
• Expected - 0 % VAT.
• Reason - the module receives only one address, but there is no VAT number in the delivery address.
