Some import test failures do not show step number

### terraform-plugin-testing version

```
github.com/hashicorp/terraform-plugin-testing v1.13.2
```

### Expected Behavior

A failed `ImportState` test step should output the step number in the error message

### Actual Behavior

If the `id` value is not found in the state, the following error message is displayed

> testing_new_import_state.go:326: Failed state verification, resource with ID tf-acc-test-3081637648281410872 not found
