Fixes: #13805
Before the fix:
```
Error refreshing state: 1 error(s) occurred:
* logentries_logset.logset: logentries_logset.logset: No such log set with key 278e7344-1201-43ba-9804-77b9a72fe7d6
```
After the fix:
```

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.

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.

Moving the transformer wholesale looks like it broke some tests, with
some actually doing legit work in normalizing singular resources from a
foo.0 notation to just foo.
Adjusted the TestPlanGraphBuilder to account for the extra
meta.count-boundary nodes in the graph output now, as well as added
another context test that tests this case. It appears the issue happens
during validate, as this is where the state can be altered to a broken
state if things are not properly transformed in the plan graph.
This fixes interpolation issues on grandchild data sources that have
multiple instances (ie: counts). For example, baz depends on bar, which
depends on foo.
In this instance, after an initial TF run is done and state is saved,
the next refresh/plan is not properly transformed, and instead of the
graph/state coming through as data.x.bar.0, it comes through as
data.x.bar. This breaks interpolations that rely on splat operators -
ie: data.x.bar.*.out.
