[FIX] manufacture: Automation rules raise traceback

Issue

    - Install `Manufacture` and `Purchase`
    - Go to `Manufacture`
    - Enable Studio
    - Create new rules
    - Select `Purchase Order` model
    - Try to select autocomplete proposition with `Deliver to` field

    Traceback raised.

Cause

    The _search function does not return indexable value.

Solution

  Cast _search to a list.

  PS: search can be used (instead of _search) to get iterable value.
