mocalculate data on MO does not bring the product_UOM

[anajuaristi]

Create a bill of materials with a product in KG
Go to manufacturing order
Calculate data
The assigned product UOM in "planned materials" is Unit, so it's wrong and it's causing this error:

Field(s) product_uom failed against a constraint: You try to move a product using a UoM that is not compatible with the UoM of the product moved. Please use an UoM in the same UoM category.

This issue was reported by me and @ybofr on this PR but you said it was not related to new hooks. I think it is, since the error appairs with "calculate data" button.

And it's not related, @anajuaristi, as just checked by @oihane. Please don't add noise and wait if you have already allocated a person for checking, then wait for her results and report it with more data.

Tested in runbot _base database:

1. Install mrp: OK
2. Install mrp_operations: OK
3. Install mrp_hook: OK
4. Install mrp_operations_extension: OK

In each step I created a BoM and I added "Ice Cream" as component (it has 'kg' as UoM) and it worked OK
After I created a MO with the product of the BoM I've just created and pushed the button "Calculate Data" it also worked OK

So I think you are not doing correctly the tests.

Ok. It could be it's not related exactly to that module but somehow, somewhere is happening. It's because of that i opened the issue. Just to not forget and try to solve it.

This is where it happens: https://github.com/OCA/manufacture/blob/8.0/mrp_bom_reference_selection/models/mrp_bom_line.py#L38
