I realize this was a pre-existing bug, but I want to discuss it now as I just saw it, and this may compromise this bundle: surely we should only do this ```_classes_copy``` if we have ```!service_check_running_${canonified_service_name}_ok```?

Otherwise, in the case that ```!service_check_running_${canonified_service_name}_ok```, there are *two* ```_classes_copy``` to the same destination class_prefix... That's got to be messed up, right?
