[FIX] l10n_it_stock_ddt: picking type

The test `test_ddt_flow` was failing because the picking types were created
without a ddt sequence. This is because the picking types were created
at the moment the company was created. However, the country of the company
was set after the setup of the CoA. This means that when we were creating
the picking types, the company's country was not Italy, therefore no
DDT sequence was created.

This commit fixes this by overriding the `setup_company_data` method to
add the country while creating the company and its CoA.

Fixes runbot error 24396 & 24397
