Bug 25545: Add adjustments to total tax included

Adjustments are not affected by tax, they are meant as a way to alter invoice
values after receiving (damaged items, refuneds, extra charges, etc)

When adjustments were added the tax included column was missed

To test:
- Add a basket with at least one order
- Close it
- Receive shipment
- Receive the order
- Finish receiving
- Add an adjustment of any amount
- Verify in the invoice details table:
  - Total tax exc. is showing including the adjustmnt
  - Total tax inc. is missing the adjustment
- Apply patch
- Reload
  - Total tax exc. is showing including the adjustmnt
  - Total tax inc. is showing including the adjustment
