[FIX] l10n_ch: fix the qr_iban fields to only appear for Swiss companies

Steps to reproduce the bug :
- Create a French company
- Go to accounting settings > in “Fiscal Localization” install French accounting
- Install “l10n_ch_qriban”
- Go to contacts > Configuration > Bank accounts
- Create a new bank account > add a French company newly created in the “Account Holder” field

Problem:
The specific fields to a Swiss company appear.

Solution :
Check if the country of the company encoded in the “Account Holder” field is Switzerland.
