Description of problem:Error on topology if cluster is low on resources for knative service


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


How reproducible: Intermittent


Steps to Reproduce:
1. Not easy to reproduce as this scenario occurs if cluster is low on resources for knative service UI shows underlying Deployment and thus now the sidebar is trying to open up a Knative sidebar when it needs a Deployment sidebar. It fails to match up the model used for this particular workload and hits a NPE failing to get it.


Actual results: Console shows error with white screen


Expected results: Error shouldn't be shown


Additional info: 
NPE happens here: https://github.com/openshift/console/blob/master/frontend/packages/knative-plugin/src/components/overview/KnativeResourceOverviewPage.tsx#L60
