update-context is confusing with profiles: "IP was already configured"

[tstromberg]

$ ./out/minikube update-context -p minikube
🙄  IP was already correctly configured for 192.168.39.232

$ kubectl config view | grep current
current-context: v1134

$ ./out/minikube update-context -p v1134
🙄  IP was already correctly configured for 192.168.39.241

$ kubectl config view | grep current
current-context: v1134

Notice how the context never changes, but minikube thinks it is already correctly configured?

I think this is just a case of confusing output. "update-context" shouldn't update the current kubectl context.

If the message simply output the name of the profile, it would seem correct.
