Fixes:#11750
Before this change, adding a log_subscription_filter and then deleting
it manually would yield this error on terraform plan/apply:
```
% terraform plan ✹ ✭

```
After this patch, we get the following behaviour:
```

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.

A couple interpolation tests were using invalid state that didn't match
the config. These will still pass but were flushed out by an attempt to
make this an error. The repl however still required interpolation
without a config, and tests there will provide a indication if this
behavior changes.
It turns out that a few use cases depend on not finding a resource
without an error.
The other code paths had sufficient nil checks for this, but there was
one place where we called Count() that needed to be checked. If the
existence of the resource matters, it would be caught at a higher level
and still return an "unknown resource" error to the user.
For historical reasons, sets are represented as sparse lists in a
flatmap, however a computed set does not have a numeric index.
Strip the `~` flag from a computed set's index during expansion, and add
it back in the prefix after sorting.

When manually deleting an autoscaling_group from the console, a
terraform plan would look as follows:
```

persisted to local or remote state storage.
