    Don't pass defaults as parameters for TemplateResource

    The child_params calculation doesn't differentiate parameters
    provided via the properties vs those provided via the template
    defaults (defined in the nested stack template), which leads to
    confusing results when you look at the parameters for the nested
    stack, as the defaults are exposed as parameters passed in
    to the stack, when the parent didn't pass anything via properties.
