`AutocompleteSelect` that I use in `django` admin panel (to have a drop-
down from which I can choose an object) **is broken**.

`self.field` should be a `Field` instance not a `QuerySet`. Moreover
autocomplete works for me. It looks like an issue in 3rd-party package
(see similar reports for autocomplete e.g. #32619 and #32659).
