Fixes#9654
Before the fix, I created an ASG with a schedule on it. Went to the AWS
console and deleted the schedule. A terraform plan looked as follows:
```
% terraform plan
See https://www.terraform.io/docs/internals/internal-plugins.html
Refreshing Terraform state in-memory prior to plan...
The refreshed state will be used to calculate this plan, but
will not be persisted to local or remote state storage.
aws_launch_configuration.foobar: Refreshing state... (ID:
terraform-test-foobar5)
aws_autoscaling_group.foobar: Refreshing state... (ID:
terraform-test-foobar5)
aws_autoscaling_schedule.foobar: Refreshing state... (ID: foobar)
Error refreshing state: 1 error(s) occurred:
* aws_autoscaling_schedule.foobar: Unable to find Autoscaling
* Scheduled Action: []*autoscaling.ScheduledUpdateGroupAction(nil)
```
After the fix:
```
terraform plan 1 ↵
Refreshing Terraform state in-memory prior to plan...
The refreshed state will be used to calculate this plan, but
will not be persisted to local or remote state storage.
aws_launch_configuration.foobar: Refreshing state... (ID: terraform-test-foobar5)
aws_autoscaling_group.foobar: Refreshing state... (ID: terraform-test-foobar5)
aws_autoscaling_schedule.foobar: Refreshing state... (ID: foobar)
The Terraform execution plan has been generated and is shown below.
Resources are shown in alphabetical order for quick scanning. Green resources
will be created (or destroyed and then created if an existing resource
exists), yellow resources are being changed in-place, and red resources
will be destroyed. Cyan entries are data sources to be read.
Note: You didn't specify an "-out" parameter to save this plan, so when
"apply" is called, Terraform can't guarantee this is what will execute.
