[V4] radio with nested fields doesn't taken initial values

[bzd2000]

Versions

• vee-validate: 4.0.0-alpha.13
• vue: 3.0.0

Describe the bug
In case of a radio group with nested fields (but i think also with non-nested fields), the initialValues are not taken into account.

To reproduce
This test case fails:

test('supports radio inputs with check after submit (nested)', async () => {
    const initialValues = { test: { fieldOne: 'one' } };

    const showFields = ref(true);
    const result = ref();

    const wrapper = mountWithHoc({
      setup() {
        const values = ['one', 'two', 'three'];
        const onSubmit = (formData: Record<string, any>) => {
          result.value = formData.test;
        };

        return {
          values,
          onSubmit,
          initialValues,
          showFields,
          result,
        };
      },
      template: ` 
      <VForm  @submit="onSubmit" :initialValues="initialValues" >
      
      <label v-for="(value, index) in values" v-bind:key="index">
              <div v-if="showFields">

        <Field name="test.fieldOne" as="input" type="radio" :value="value" /> {{value}}
        </div>
              </label>
    
        <button>Submit</button>
        <div>{{$result}}</div>
      </VForm>
    `,
    });

    // const err = wrapper.$el.querySelector('#err');
    const inputs = wrapper.$el.querySelectorAll('input');
    await flushPromises();
    expect(inputs[0].checked).toBe(true);

    setChecked(inputs[1]);
    await flushPromises();
    wrapper.$el.querySelector('button').click();
    await flushPromises();
    showFields.value = false;
    await flushPromises();
    expect(result.value.fieldOne).toBe('two');
  });

Expected behavior
InitialValues are taken in to account.
