Cached computed values are not invalidated when state ancesters are removed

Given a Computed:

export default Computed({
  value: 'parent.value'
}, ({ value }) => value ? value * 2 : 'missing')

The computed response will not return 'missing' when parent is deleted from the state tree, it will return an older cached response.

Ah I see @garth. So, I would say this is definitely a bug. 😃 All child paths need to get marked as changed if their parent is deleted (or updated). I think that logic should always be the case.
