Errors doesn't clear on change while using `onBlur` mode

Describe the bug I’m not sure if this is a bug. But while using onBlur mode, errors don’t clear when a field is changed like they do while using onSubmit mode.

To Reproduce Here is a recreation.

Expected behavior I expect the errors to be cleared when the corresponding field changes.

I think @Tymek 's right - if you have an error and you correct it (regardless of mode), the error should clear on the change, so you know it happened… I’d like to hear a scenario where that would be unwanted.

Hey @bluebill1049, thanks to you and everyone else for this awesome library.

I mentioned this on #283, but I figured it applied more here.

How can I 1) show an error onBlur, and 2) clear an error onChange?

I tried this:

useForm({ mode: 'onBlur', reValidateMode: 'onChange' })

This is great for showing an error on blur, but it also only clears the error on blur, not on change. Is there something wrong with that implementation?

Code sample here: https://codesandbox.io/s/react-hook-form-get-started-forked-vkk9j?file=/src/index.js:0-748

you want to use mode: onTouched, reVliadateMode is for after submit
