Deleting the bootstrap app hangs while deleting the entire hierarchy

[noam-codefresh]

We currently have the following hierarchy:
bootstrap app -> cluster-resources appSet -> in-cluster app -> argocd-ns Namespace Resource
inside the argocd-ns Namespace we install the bootstrapped argocd.
When we delete the bootstrap app, the cascading causes the Namespace to be deleted, which in turn deletes the Argo CD controllers. After that, the remaining applications are stuck in "terminating" state, since their finalizer can not run.
