Arvados

The `arv` commands that failed with that error are being executed on the CI server. I fixed it this way:

ci:~# arv

ARVADOS_API_HOST and ARVADOS_API_TOKEN need to be defined as environment variables.

Future improvement: run the deploy script from a clean environment (e.g. jenkins slave or docker container).
