crwctl server:delete leaves resources behind, please fix

Under some (maybe all?) circumstances, crwctl leaves artifacts behind. Please fix so the cleanup is complete.

• the "workspaces" project is left behind

• Others can be viewed via
  $ oc api-resources --verbs=list -o name | xargs -n 1 oc get -o name | egrep -i '(codeready|che|workspaces|keycloak|postgres)'
