Operator does not revoke roles when removed from the PulsarPermission's CR

[brunocascio]

1. Create the following permission

apiVersion: resource.streamnative.io/v1alpha1
kind: PulsarPermission
metadata:
  name: devops-techweek-permissions-foo
spec:
  connectionRef:
    name: pulsar-connection
  resourceType: topic
  resourceName: persistent://test/devops-techweek-dev/foo
  roles:
  - role-1
  - role-2
  actions:
  - produce
  - consume

1. Remove some of the roles

apiVersion: resource.streamnative.io/v1alpha1
kind: PulsarPermission
metadata:
  name: devops-techweek-permissions-foo
spec:
  connectionRef:
    name: pulsar-connection
  resourceType: topic
  resourceName: persistent://test/devops-techweek-dev/foo
  roles:
  - role-1
  actions:
  - produce
  - consume

The operator does not revoke that access

Guess it could be sort of related to this issue as well #255
