Empty option is not selected if field is empty, using the radio buttons widget

I added a possible fix. Only tested OptionsButtonsWidget though, probably needs testing with other field types extending OptionsWidgetBase. Also needs tests.

Added one more condition to the existing fix($field_type === 'boolean') and also added tests, please review

@DieterHolvoet, thanks! it would be nice to having this working as expected.

The IS is clear and there is a proposed resolution. Thanks.

Reading the comments there is an unanswered question in #3. Thank needs to be done.

With that question in mind I applied the change and tested. This works fine for boolean fields. I then tested with an integer list field and the problem still existed. I think a general solution for all fields using the 'Check boxes/radio buttons/' display is needed.

And then I looked at the code and this is just applying the fix to booleans, if ($field_type === 'boolean' &&.

Setting back to needs work.
