Bug reported by customer: https://access.redhat.com/support/cases/#/case/04185008

Description of the problem:
When the orchestrator is installed on existing RHDH and helm chart is used deploy RHDH we get "error": "no matches for kind \"Backstage\" in version \"rhdh.redhat.com/v1alpha3\""

How reproducible:
Install RHDH using helm chart and add the orchestrator to existing RHDH.

Actual results:

The controller fails with:
