scoping juju calls to controller

In my local environment I may have Zaza performing tests on one juju controller (i.e. localhost-localhost) and at the same time using my juju environmet to interface with a local or remote maas controller.
If I have a model on a different controller in focus Zaza will bomb out.
Example Traceback:
