[FIX] website_sale: fix prices on Products snippet on branch website

Steps to reproduce:
- Create a branch for a company (e.g. Branch X)
- Go to "Website / Configuration / Websites"
- Create or configure a website on Branch X (e.g. Website X)
- Go to "Website / Configuration / Settings"
- Select Website X
- Set "Display Product Prices" to "Tax Included"
- Create a product for a price of $100 and a tax from parent company (e.g. 15%)
- Go Website X
- Edit Home page and add Products snippet

Issue:
On the Products snippet, the price of the product should be "Tax Included" ($115),
but it is not. The displayed price is $100.

Cause:
When computing the prices, taxes from parent companies are not taken into account.
