  Avoid duplicate IDs when using `QuerySourceRadioWidget` for non-required fields. (#62)

Avoid duplicate IDs when using `QuerySourceRadioWidget` for non-required fields.

The `items` method in `z3c.formwidget.query.widget.QuerySourceRadioWidget` creates for the empty value an input element with `-novalue` as ID-suffix. The base class RadioWidget generates in the method `renderForValue` two input elements with `-0` as ID-suffix - both for the special `--NOVALUE--` item and the regular first item. Keep using the `-novalue` variant in the first case.
