Describe the bug
In the "Pods" view of an Application, when grouping by "Parent Resource" if there exists a pod in said Application that does not have a parent, the UI crashes.

To Reproduce

1. Create an Application in ArgoCD
2. Add a Pod to the Application created in 1. without a controller (i.e. ReplicaSet/Job/Deployment/etc.)
3. Login to ArgoCD UI
4. Navigate to the Application created in 1.
5. Open the "Pods" view
6. Group by "Parent Resource"
7. It crashes with the following stacktrace 😢

Expected behavior
Instead of the UI crashing, the view should show up and maybe list the Pod as the "Parent Resource" for itself.
