form.setFieldValue on an un-initialized field will create meta missing errors #1078

Describe the bug

If you have a field that is displayed conditionally in the form, and use form.setFieldValue without dontUpdateMeta: true before it's initialization, it will create meta for this field without errors. I understand that makes more sense to update the value with dontUpdateMeta: true if the field wasn't initialized yet, but it can lead to some inconsistent behavior since we are not expecting errors to be undefined.

Your minimal, reproducible example

Steps to reproduce

Expected behavior

After clicking on setFieldValue meta shold include errors array even before the element initialization

Hi all 👋

Can confirm this also took me off guard. Has this always been the case?
