    Short-circuit local delete path for cells v2 and InstanceNotFound

    When we're going down the local delete path for cells v2 in the API
    and instance.destroy() fails with an InstanceNotFound error, we are
    racing with a concurrent delete request and know that the instance
    is alread deleted, so we can just return rather than fall through to
    the rest of the code in the _delete() method, like for BDMs and
    console tokens.
