[FIX] stock_dropshipping: create missing dropship picking type

In the function `create_missing_dropship_picking_type()`, the way to
search companies that already have dropship picking type was not robust
enough as it used the translatable `name` field in a search domain and
the ORM `search` method used the translated value of `Dropship` name value
instead of the raw value.
A better approach is to search `stock.picking.type` with a default source
location usage set to `supplier` and a default destination location usage
set to `customer`.
