Bug: PR 2327 introduces regression in vm

[davidnixon]

Describe the bug

This change
#2327
broke my test case.

To Reproduce

Pull this PR
carbon-design-system/carbon-components-vue#1662
Run
yarn test src/components/CvAccordion/__tests__/CvAccordion.spec.js

The change in the PR #2327 removes the visibility of componentRef in the vm. It maybe related to the component using defineExpose({ state }); which is not used elsewhere in our components.

Reverting the change on #2327 fixes the test case.

Expected behavior

    const acc = wrapper.findComponent(`.${carbonPrefix}--accordion`);
    expect(Boolean(acc.vm.componentRef)).toBe(true);
