Subject: [PATCH] [FIX] stock: forecast quantity only on warehouse

Before this commit, forecasted quantity in the product stat button and
in graph/grid view wasn't always equals.
The issue was the forecasted quantity is based on quant in location who
is child of warehouse location, and the `report.inventory.quantity` used
in graph/grid view didn't filter on warehouse location (took all
internal location).
So, completes the domain on `report.inventory.quantity` to get only
quantity in the warehouse.
Same change is applied to the Forecasted Inventory report.

Task #2058665
