In commit f8dad1bb4b, we tried to fix the currency
conversion of products by always using the currency of the product as the base.
This is still correct.
However, the conversion method also needs to know the company (to find the
correct currency rate), and it was assumed the company was also always set on
the product. This is of course not correct when using multi-company.
In this commit we fix that issue by falling back if no company is set on the
product. The order of the fallback is: product website company, given website
company, given pricelist company, current user company.
