[FIX] payment,sale: Use record website domain in links

Steps:
- Go to Settings > Users & Companies > Companies
- Create a new company (1)
- Install a payment acquirer and Website
- Go to Website > Configuration > Settings:
- Select "My Website 2"
- Assign it to company (1)
- Add a custom domain
- Save
- Switch to company (1)
- Go to Invoicing
- Create a new Invoice:
  - Add a product line
- Post it
- Click Action > Generate a Payment Link

Bug:
The base domain is used instead of the domain of the website linked to
the invoicing company.

Explanation:
The app only uses the URL on which the user has logged in to generate a
payment link. If the user has multiple companies, this can confuse
customers if they land on another domain than the one they are used to.
This commit makes the app use the domain of the website of the record
linked to the payment if it has one.
