e2e tests leave resources behind after running

What broke? What's expected?

Running e2e tests leaves cert-manager related resources behind, causing failures in subsequent runs.

Namely, the resources leases.coordination.k8s.io/cert-manager-cainjector-leader-election and leases.coordination.k8s.io/cert-manager-controller in the kube-system namespace.

Reproducing this issue

Run make test-e2e then kubectl get -n kube-system leases.coordination.k8s.io
