useComboBox + useAsyncList does not show results after a call that was after a call that returned an empty list

### Provide a general summary of the issue here

We use Asynchronous loading with useComboBox.

We use useAsyncList as shown in the [documentation](https://react-aria.adobe.com/ComboBox/useComboBox.html#asynchronous-loading).

When we write something and the API returns no results, the next call does not update the comonent items, even if there are matching results.

We thought it was a bug on our side but we saw that the provided example had the same problem.

### 🤔 Expected Behavior?

Pressing "backspace" after writing "luka" should show "Luke Skywalker"

### 😯 Current Behavior

Pressing "backspace" after writing "luka" still doesn't show the results

Open the asynchronous-loading useComboBox documentation example and reproduce the sequence: search for "luka" until the list is empty, then press backspace. Inspect the useComboBox and useAsyncList entry points involved in updating the ListBox; done means the matching result appears after the second request, including after an empty response.
