Failed to preview stack with template resource nested in resource group

[Oleksii Chuprykov]

Preview stack with such templates:

outer.yaml: http://paste.openstack.org/show/487884/
inner.yaml: http://paste.openstack.org/show/487885/

heat stack-preview abc -f outer.yaml
Heat responses with ERROR: The Parameter (fixed_network_id) was not provided.

It seems that preview_resources() is broken.

    Fix stack preview

    Don't execute translation rule for property that contains
    a GetParam function that can't be resolved at the moment.
    Such situation happens when we try to resolve get_param function
    that refer to parameter with None value. We receive parameter value
    from parent stack, where this value is a reference to some resource
    without resource_id, so this situation is legal for stack preview
    and we shouldn't fail. Note, that we can reproduce this behaviour
    only with resources with hidden parameters and overrided get_resource_id
    method, that returns None if resoruce creation has not been started yet.
