Terraform destroy fails if Data Source referred resource is desroyed manually

[ghost]

This issue was originally opened by @rahulpatil18 as hashicorp/terraform#18385. It was migrated here as a result of the provider split. The original body of the issue is below.

---

Problem Statement-

If the resource(Lets call it foo) is deployed with the help of data source, If the resource(bar) which is referred by data source is already destroyed by manually or by accident, terraform destroy fails while destroying the resource(foo)

Terraform Version - v0.11.6

For example -

---

data "aws_security_group" "selected" {
id = "SG-ID"
}

output "group_name" {
value = "${aws_security_group.name}"
}

---

If we try to destory above resource when resource which id (SG-ID) we provided is no more available, Terraform will fail to destroy the resource

Expected Behavior

It should destroy the resources regardless of resources availbility which are refered by data source.

Actual Behavior

It fails to destroy resources

Steps to Reproduce

1. Use data source resource while creating the resource (Terraform deploy)
2. Destroy the resource which data source is referring to (manual step)
3. Try to Destroy the resource (Terraform destroy)
