In PR kubernetes#3426, I changed "minikube start" to overwrite the cluster config earlier so that the container runtime could be extracted from it by the buildroot provisioner. This introduced a bug later on, where minikube expected to read the kubernetes version from theold config (which no longer existed, because the config was overwritten). To fix this, I changed the code to store the old version of the config in memory before overwriting it. This should fix kubernetes#3447
