Project view does not show project direct costs

[Patch]

I suspect it is related to

Projects' Direct Cost Includes Purchase Orders

In the latest version (22.6.8.78), Project column on line items of purchase invoice won’t be visible if purchase invoice is linked to purchase order. This will avoid duplicate cost issue where both purchase order and purchase invoice have projects defined. This is simple solution but it’s important to keep this simple. When you click on the list of costs in the project, drilling-down into original entries need to be as straightforward as possible.
