docker run --demo doesn't work with Edge Stack

[kflynn]

If you run

docker run -it -p 8080:8080 --name=ambassador --rm quay.io/datawire/aes:1.0.0 --demo

per https://www.getambassador.io/about/quickstart/, it blows up:

time="2020-01-23 15:10:01" level=error msg="error reading license key: open /root/.config/ambassador/license-key: no such file or directory"
time="2020-01-23 15:10:01" level=info msg="Ambassador Edge Stack configuation loaded"
time="2020-01-23 15:10:01" level=error msg="shut down with error: the server is currently unable to handle the request"

There are also errors from the dev portal, though those aren't the thing that causes the crash:
