Fix minikube start args for integration tests (#4885)

I've been seeing errors like `Error running command: -p=TestPersistence start --vm-driver=hyperv --hyperv-virtual-switch=primary-virtual-switch --bootstrapper=kubeadm--wait=false --v=10 --logtostderr  --alsologtostderr --v=2 . Output: * minikube v1.2.0 on windows (amd64)` in my hyperV testing which means we need an extra space here.
