Fails if there's no config in ~/.kube

[tarekmehrez]

I have 3 different contexts, all set in KUBECONFIG.
kube-prompt fails when I try to get a certain pod or service

>>> get pods panic: stat /Users/tarekmehrez/.kube/config: no such file or directory

goroutine 36 [running]:

Is there a way that this might work just by checking my current context?

Same as #10.
