feat(api): fix $validate API when using touched (#211) by @losadaem

Add touched option to `willUpdateFlags` in `RadioValidation` and
`CheckboxValidation` classes.

In 4635ce4 $validate API was updated with touched option. But this
was not implemented in `BaseValidation` subclasses.

Add tests for all validatable elements

Fixes: #210
