When you want to obtain `dropship_picking_type`, it is possible to have
several results. This will lead to an error when doing
`dropship_picking_type.id`.
```
dropship_picking_type = self.env['stock.picking.type'].search([
('company_id', '=', company.id),
('default_location_src_id.usage', '=', 'supplier'),
('default_location_dest_id.usage', '=', 'customer'),
])
```
The fix ensures that `dropship_picking_type` contains only one element.
