fix(form): simplify blur and respect revalidation

The validation triggered by change and blur are similar. However, the code was unneccesary different.
Additionally the blur validation did not respect a possible given revalidate:false resulting in revalidating error fields all the time when the field blurs (even if one only wants revalidation on submit)

It also fixes not showing/updating the error messages on blur as change does
