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.

Fixes: #12279
When manually deleting an autoscaling_group from the console, a
terraform plan would look as follows:
```
% terraform plan
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: test-0096cf26c7eebdc9fcb5bd1837)
aws_autoscaling_group.foobar: Refreshing state... (ID: test)
aws_autoscaling_schedule.foobar: Refreshing state... (ID: foobar)
Error refreshing state: 1 error(s) occurred:
* aws_autoscaling_schedule.foobar: aws_autoscaling_schedule.foobar: Error retrieving Autoscaling Scheduled Actions: ValidationError: Group test not found
status code: 400, request id: 093e9ed5-fe01-11e6-b990-1f64334b3a10
```
After this patch:
```

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.

Add Env and SetEnv methods to command.Meta to retrieve the current
environment name inside any command.
Make sure all calls to Backend.State contain an environment name, and
make the package compile against the update backend package.
What will hopfully be the final version of the Backend interface. This
combines the MultiState interface into Backend since it will be required
to implement, and simplifies the interface because the Backend is no
longer responsible for tracking the current state.
Destroying a terraform state can't always create an empty state, as
outputs and the root module may remain. Use HasResources to warn about
deleting an environment with resources.
