[FIX] product_sale_price_from_pricelist: Handle product.template in _compute_price_rule

Added check to ensure _compute_price_rule always works with product.product.
When product.template records are passed, convert them to their variants
before processing. This prevents MissingError when browsing product.product
with template IDs.

Fixes: Record does not exist or has been deleted (Record: product.product(22,))
