This fix ensures that when creating cut-off journal entries from vendor bills that include vehicles, the vehicle information is properly retained in the generated journal items. Previously, the vehicle ID was being lost during the cut-off process, which could cause tracking and reporting issues for fleet-related expenses.

Create a Vendor Bill
Add on the invoice line a vehicle
Confirm
In "Journal Items" tab hit 'Cut-Off'
Fill the necessary info and create journal items
Issue: Created journal items will not have the vehicle id
