    4. Send PO from second company over as email.
    5. Check recipient email (or mailhog for Runbot) for the email
    6. Find that while the PDF report reflects second company's logo,
        the header navigation bar in the client email when clicking "View Request
        for Quotation" reflects company_id=1's logo.
