Original issue's description:
> Telemetry: Fix exact_matches in telemetry.test_runner.
>
> Previously, if exact_matches was True but there were no exact matches,
> it would return fuzzy matches instead. This is not what the caller asked
> for.
>
> GPU test names are changed to match the buildbot config, since they were
> previously relying on fuzzy matching.
>
> SHERIFFS: May cause errors like:
>
>   No test named "some_test_name".
>
>   Available tests are:
>     ...
>
> If so, this CL can be safely reverted.
