At stock installation, the warehouse0 has the name of the first company found
(order "sequence, name"), while the comapny_id field is
`_company_default_get('stock.inventory')` (the company of the user installing
the stock module).
In a multi-company environment, it is possible than both results are different
and having name = 'Company A' and company_id = 'Company B'.
Use the name of the default company as default value for the field name.
Note that 'stock.inventory' is not needed in _company_default_get call but
kept to match the default of company_id (in case of override).
Using a default on the field will impact all the future records but should,
hopefully, not be problematic as it is a valid default value.
