Required Validation does not disappear with formio 5.0.0-x

[ralfeis]

Hi,

if I use the newest version 5.0.0-rc38, then the "required" validation behaves different to the 4.6 version of formio.

The example is a "true","false" decision which must be selected (required validation) If "no" is selected, then the required validation does not disappear.

Here is a simple example to test: https://stackblitz.com/edit/js-o27pu6?file=index.html,package.json
