The FilterButton is present with all filters children having the alwaysOn option being set

[soullivaneuh]

What you were expecting:

When I have all my filter being show by default:

const UserFilter: FC<Omit<FilterProps, 'children'>> = (props) => (
  <Filter {...props}>
    <SearchInput source="$search" alwaysOn />
    <BooleanInput source="isDriver" label="Chauffeur" alwaysOn />
  </Filter>
);

The additional filter button should not appears.

What happened instead:

The button appears with an obvious empty filter list, making it useless.

Steps to reproduce:

Checkout the following PR and start the application.
