[FIX] l10n_din5008: hide all header if not needed

Steps to reproduce:
- Install Accounting and l10n_ch
- Switch to a Swiss company
- Go to Settings and make sure that DIN5008 is selected as Document Layout
- Go to Accounting settings and activate "QR Codes" option
- Create an invoice for an Swiss contact
- Print the invoice
=> The DIN5008 header is appearing on the QR code page.

No header should appear on the QR code page with DIN5008.
