No manual changes.

The patch correctly identified the metadata problem but did not skip
over when collecting the group metadata for the restmapper.

Fixes https://github.com/kubernetes/minikube/issues/1252

TPRs are incorrectly coupled with the RestMapper right now.  The real
solution is for TPRs to not register themselves with the RestMapper.
This is a short term patch for minikube until the work is done
upstream.  On start/stop, the namespace controller and the garbage
collector controller both call this code and panic since TPRs have
registered themselves with enabled versions but have no group metadata.
