Select empty_select documentation incorrect

[abraxxa]

https://metacpan.org/pod/HTML::FormHandler::Field::Select#empty_select states: 'This only affects rendering - it does not add an entry to the list of options.' which doesn't seem to be true. At least when calling $field->render it includes an option with the id 0. Seems to happen in https://metacpan.org/source/GSHANK/HTML-FormHandler-0.40067/lib/HTML/FormHandler/Widget/Field/Select.pm#L62.
