juju set-default-region aws us-west-2 does not actually update the default as shown below:

@John George,

I cannot reproduce this using current tip of 2.7, heading into 2.7.1. Maybe the problem is fixed on the next release lined up?

This is the output I get: https://pastebin.ubuntu.com/p/MDPPJvPTnS/.
