Comment 4 for bug 1505504

We've been clearing the current model for a while now, but we've still been printing out an ugly/invalid error message that states there's no current controller. I've got a PR that will change this to correctly state that there's no current model, and how you can go about setting one.

$ juju status
ERROR no model specified

There is no current model specified for the current controller,
and none specified on the command line. Please use "juju switch"
to set the current model, or specify a model on the command line
using the "-m" flag.
