Using yup with onChange or onBlur mode

Describe the bug onChange and onBlur mode doesn’t work with yup validation schema or I miss something 😃

To Reproduce Steps to reproduce the behavior:

1. Open ValidationSchema example: https://codesandbox.io/s/928po918qr
2. Set mode: 'onBlur:

const { register, handleSubmit, errors } = useForm({
    mode: 'onBlur',
    validationSchema: SignupSchema
  });

1. Change the firstName and/or age fields and watch stringified errors object.

It looks like that clearing error works OK, but setting error does not.

Expected behavior Expected error message for empty firstName field after leaving field.

Desktop (please complete the following information):

• OS: macOS 10.14.4
• Browser chrome, 73.0.3683.103

Oh man, nothing to apologize for! My day is just starting as yours is ending. This was a great turnaround time. FYI I’ve already got your library in production and it’s going to be part of every form in the project, it’s providing a great value already. Thank you for all your hard work.

😮!

I saw reValidationMode and assumed from the lack of plain validationMode that it handled 100% of the operation. Thanks for the clarification!
