Currently, when creating a purchase order, if the product has multiple vendor lines (with the vendor selected on the PO), the product description uses information from all the vendor lines; instead of using information from the vendor line that is used for the price.
Steps to reproduce:
-------------------
* Go to the **Purchase** App
* Go to **Products**
* Select any product
* Select the **Purchase** tab
* Add `Vendor Product Name` and `Vendor Product Code` in additional line fields
* Add two vendor lines
* Line 1:
`Vendor`: Vendor1
`Vendor Product Name`: P1
`Vendor Product Code`: A
`Price`: 1
* Line 2: <br>
`Vendor`: Vendor 1
`Vendor Product Name`: P1 bis
`Vendor Product Code`: B
`Price`: 5
* Select **Orders** > **Request for quotation**
* Create a new quotation
* Select Vendor 1, add the product for which we just added the two vendor lines
> **Observation**: The description of the product shows information from both vendor lines added.
Why the fix:
------------
This behavior was introduced when `name_get` was removed to use `dispay_name` instead.

When adding a product to the purchase order, the onchange on `product_id` is called. The onchange calls the function `_product_id_change`, which itself calls `_get_product_purchase_description`.
https://github.com/odoo/odoo/blob/7e9b9494a8d6c4bb8b3800cc0e25fcd3596db75d/addons/purchase/models/purchase.py#L1224https://github.com/odoo/odoo/blob/7e9b9494a8d6c4bb8b3800cc0e25fcd3596db75d/addons/purchase/models/purchase.py#L1401-L1407
The line `name = product_lang.display_name` calls the function `_compute_display_name`.
* We do have a parnter_id in the context as we have selected a vendor on the purchase order.
https://github.com/odoo/odoo/blob/7e9b9494a8d6c4bb8b3800cc0e25fcd3596db75d/addons/product/models/product_product.py#L434
* We don't have a supplierinfo in the context yet but we have multiple supplierinfo with the same partner_id.
https://github.com/odoo/odoo/blob/7e9b9494a8d6c4bb8b3800cc0e25fcd3596db75d/addons/product/models/product_product.py#L466-L467
Here we thus have 2 sellers.
* Ultimately, the display name joins the different display names computer for each seller.
https://github.com/odoo/odoo/blob/7e9b9494a8d6c4bb8b3800cc0e25fcd3596db75d/addons/product/models/product_product.py#L473-L483
Coming back to the line `self.name = self._get_product_purchase_description(product_lang)`, we now have the name of the purchase order line set as the concatenation of display names from the supplierinfo, i.e `'[A] P1, [B] P1 bis'`.
Once the onchange is called, the function `_compute_price_unit_and_date_planned_and_name` is being called.
https://github.com/odoo/odoo/blob/7e9b9494a8d6c4bb8b3800cc0e25fcd3596db75d/addons/purchase/models/purchase.py#L1295
In the current state, we do not meet the if condition. Indeed, the line has a name (`'[A] P1, [B] P1 bis'`) but it isn't in the default_names (`['[A] P1', '[B] P1 bis']`). It somehow corresponds to a setting where the name of the purchase order line was setup by the user.
With this current fix, the call to `_product_id_change` will set the name of the line with the product information from the company; and not the partner. We also need to add this name to the `default_names` in `_compute_price_unit_and_date_planned_and_name` so that the description get recomputed with regards to the seller, if any.
