Description of problem:

When viewing a Pipeline that shares the same name as the Task (and it's taskRef name) it does not render in the visualization.

Prerequisites (if any, like setup, operators/versions):

OpenShift 4.5.24
Pipelines Operator 1.1.2 (ocp-4.5)

Steps to Reproduce

1. Create the Pipeline from this yaml:

   apiVersion: tekton.dev/v1beta1
   kind: Pipeline
   metadata:
     name: myapp-install
   spec:
     tasks:
       - name: myapp-install
         taskRef:
           kind: Task
           name: myapp-install
   

Actual results:

Expected results:

A visualization that renders the node.

Reproducibility (Always/Intermittent/Only Once):

Always

Build Details:

4.5.24 (with 1.1.2)
4.7.0-0.nightly-2021-01-19-095812 (with 1.2.2)

Additional info:

Reported on the Tekton Slack Workspace by someone using "IBM Cloud managed OpenShift".

Workaround would be to rename the Pipeline or Task.name and the node reappears.
