Acorn won't uninstall if the controller is in an error state

[thedadams]

If you have any project and/or an app running with a delete job and the controller is erroring for some reason, then it is not possible to uninstall the runtime. The uninstall will hang because the CRDs are not able to be cleaned up.

To reproduce:

1. Deploy runtime and deploy an app in the acorn project with a delete job.
2. Scale the controller to 0 with kubectl -n acorn-system scale deployment acorn-controller --replicas 0.
3. Uninstall the runtime with acorn uninstall -af.

The uninstall will hang. This should not happen.
