Unmounting a field does not update the form

[Christian24]

Describe the bug

Hi,

I just noticed a bug unmounting a field: the state and fieldInfo of the field is preserved in the form even after unmounting it.

To illustrate I added some expects to the unmount test:

     // Field should have been removed from the form as well
    expect(form.state.values.name).toBeUndefined()
    expect(form.state.fieldMeta.name).toBeUndefined()

These last assertions fail at the moment.

Your minimal, reproducible example

#501

Steps to reproduce

1. Run the tests
2. they fail

Expected behavior
