[FIX] payment : Wrong logo in payment portal

Current behavior :
In a multi-company environnement if you generate a payment link and access it from incognito page the company was always the logo of the first company.

Steps to reproduce :
- Get in a multicompany environnement
- Create a invoice in company B
- Generate the payment link in the action menu
- Access the link in incognito mode
- The company logo is always the logo from company A
