Before this commit, refresh the forecast report can lead to error if
this report refer to a product variant (`product.product`).
As it lost to which model the report is supposed to refer, it take the
one by default (`product.template`) which can lead to error (display a
traceback if the ID doesn't exist or display the report for another
product if the ID exists).
How to reproduce:
Open the Forecasted Report for a `product.product` (from the stat button
or from the `sale.order.line` widget for example) then refresh the page.
