Description of problem:
This is a follow-up on https://bugzilla.redhat.com/show_bug.cgi?id=2083087 and https://github.com/openshift/console/pull/12390

When creating a Deployment, DeploymentConfig, or Knative Service with enabled Pipeline, and then deleting it again with the enabled option "Delete other resources created by console" (only available on 4.13+ with the PR above) the automatically created Pipeline is not deleted.

When the user tries to create the same resource with a Pipeline again this fails with an error:

An error occurred
secrets "nodeinfo-generic-webhook-secret" already exists

Version-Release number of selected component (if applicable):
4.13

(we might want to backport this together with https://github.com/openshift/console/pull/12390 and OCPBUGS-5547)

How reproducible:
Always

Steps to Reproduce:

1. Install OpenShift Pipelines operator (tested with 1.8.2)
2. Create a new project
3. Navigate to Add > Import from git and create an application
4. Case 1: In the topology select the new resource and delete it
5. Case 2: In the topology select the application group and delete the complete app

Actual results:
Case 1: Delete resources:

1. Deployment (tries it twice!) $name
2. Service $name
3. Route $name
4. ImageStream $name

Case 2: Delete application:

1. Deployment (just once) $name
2. Service $name
3. Route $name
4. ImageStream $name

Expected results:
Case 1: Delete resource:

1. Delete Deployment $name should be called just once
2. (Keep this deletion) Service $name
3. (Keep this deletion) Route $name
4. (Keep this deletion) ImageStream $name
5. Missing deletion of the Tekton Pipeline $name
6. Missing deletion of the Tekton TriggerTemplate with generated name trigger-template-$name-$random
7. Missing deletion of the Secret $name-generic-webhook-secret
8. Missing deletion of the Secret $name-github-webhook-secret

Case 2: Delete application:

1. (Keep this deletion) Deployment $name
2. (Keep this deletion) Service $name
3. (Keep this deletion) Route $name
4. (Keep this deletion) ImageStream $name
5. Missing deletion of the Tekton Pipeline $name
6. Missing deletion of the Tekton TriggerTemplate with generated name trigger-template-$name-$random
7. Missing deletion of the Secret $name-generic-webhook-secret
8. Missing deletion of the Secret $name-github-webhook-secret
