Comment 13 for bug 1546201

I agree that will fix the template test. It doesn't fix the issue that template test raises though if a user happens to create a template similar to the current one. If we want that kind of template to fail validation, maybe that should be another bug. I'm not totally sure it should be considered an invalid case though -- the user may not really care which subnet the server gets associated with if there are multiple subnets, and the user may want to create the network/subnets/server all in one template.
