    Work around parameter error deleting backup stack

    There is a problem where restoring a backup resource which references
    a parameter in it's properties that doesn't exist in the backup stack
    will fail to delete, if the property is referenced in the delete path
    of the resource.

    We can work around the problem by always returning the frozen_definition
    properties on delete, provided there are stored properties to refer to.
