Contract report showing last line in black when used external_layout_boxed

Recurring - Contracts Management (contract)

Describe the bug

(Cosmetic Issue on report) Contract report showing last line in black background color when used external_layout_boxed in all tables, not only on totals. Also totals are shown in black no matter the company color.

To Reproduce

Affected versions:
Confirmed on 16.0 and 17.0, presumably the ones before as well.

Steps to reproduce the behavior:

1. Install the contract module
2. On general settings set the external layout to external_layout_boxed
3. Create a contract (customer or supplier)
4. Print the contract report

Expected behavior
The recurring item lines should be consistent with the rest of reports on the system for this layout (white background, totals in a different color set by company), and with the other layouts for this same report (these don't show this bottom line in a different way)

Corrections for 16.0 are compatible with 17.0, once the PR #1178 gets merged, the commit there fixing the report can be cherry-picked from 17.0

Once PR #1181 gets merged, this issue can be closed
