Subject: Switch node locations to a set and consider empty string to be empty
 set

Note that we also don't check the individual locations anymore. The key numbers will be randomized and not testing content seems to be the method employed by the AWS provider as well https://github.com/terraform-providers/terraform-provider-aws/blob/81bba6b1f567aed561c6a6a30916504ee0886c68/aws/resource_aws_autoscaling_group_test.go#L404
