The command `oc get apiservices | grep serving` gives me this :

v1alpha1.serving.knative.dev             Local                                                                   True        25h
 

And the command `oc get crds | grep serving` gives me:

knativeservings.serving.knative.dev                         2019-08-20T12:37:13Z

Steps to reproduce:

• install Serverless Operator TP1 from the catalog source (master branch)
• wait for the installation to finish and create KnativeServing CR
• delete KnativeServing CR (this removes the Knative Serving pods except for the operator
• uninstall the operator via UI (Installed Operators -> Serverless Operator -> Delete Cluster Service Version)
• oc delete catalogsource serverless-operator -n openshift-operators
• check existing api services and crds
