AutocompleteInput doesn't show 'No options' when empty value is allowed

[slax57]

What you were expecting:
AutocompleteInput should display both 'No options' and 'empty' when the empty value is allowed (and emptyText="empty") and the query returns no result.

What happened instead:
AutocompleteInput only shows 'empty' among the options.

Steps to reproduce:

1. Go to https://stackblitz.com/edit/github-varpfb?file=src/posts/PostCreate.tsx
2. Log in as admin
3. Go to PostCreate
4. Click '+' to add an author
5. Select 'Logan Schowalter' as the author
6. In the same AutocompleteInput, type in 'test'
