On a `sale.order`, when hitting the `View Forecast` button,
a traceback occurred:
```

This follows the `load_views` refactor odoo/odoo#87522.
`fields_view_get` has been deprecated. All calls to it must be replaced
by calls to `get_views`.
Leaving it there is an oversight:
https://github.com/odoo/odoo/blob/fc26cc1789b1309e54473cccbc545145ccbaee31/addons/stock/static/src/js/report_stock_forecasted.js#L116
However, this demonstrated an issue in the compatibility layer added
server-side to keep `fields_view_get`.
This revisions solves the compatibility layer bug.
In the next commit, the call to `fields_view_get` is replaced to
a call to `get_views`
