self in Module Declaration causes crash

[pearkes]

Given a module declaration like this:

module "foo" {
    source = "./bar"
    name  = "pearkes"
    foobar = "${self.name}-2"
}

Terraform crashes on:

terraform plan -module-depth=-1

Thanks, fixed in the attached PR. Self variables don't quite work that (though I'd like them to one day). For now, they simply aren't allowed in modules.
