Include resource type headers in diff report

**What this PR does / why we need it**: when checking for leaked resources, we report a failure only if there were additions to the diff - we don't want resources that were deleted during the run to count as a failure.

The logic for this removes the resource type headers from the diff report, however, so it's harder to understand what leaked.

For example, in https://k8s-gubernator.appspot.com/build/kubernetes-jenkins/logs/ci-kubernetes-e2e-gke-alpha-features-release-1.5/196/, the test failure shows
```
Error: 4 leaked resources

```

but the [actual diff](https://storage.googleapis.com/kubernetes-jenkins/logs/ci-kubernetes-e2e-gke-alpha-features-release-1.5/196/artifacts/gcp-resources-diff.txt) contains more information:

This PR will include the `[ type header ]`s in the report if resources are leaked.
