ReferenceArrayInput with AutocompleteArrayInput throws error if the array is empty

[ogroppo]

What you were expecting:
I expect the autocomplete to be empty for no references returned i.e. {data: [], total: 0}

What happened instead:
The page throws error
TypeError: Cannot read properties of undefined (reading 'length')

As soon as I create a Tag, the form is happy

Steps to reproduce:
Create a form that relies on a many-to-many rels, i.e. a classic Posts-Tags

export const PostCreate = (props: CreateProps) => (
  <Create title="New post" {...props}>
    <SimpleForm>
      <TextInput source="text" />
      <ReferenceArrayInput label="Tags" reference="tag" source="tags">
        <AutocompleteArrayInput />
      </ReferenceArrayInput>
    </SimpleForm>
  </Create>
);
