A V0 imported recipe is refused on a robot and assigned to a person when one is present

# Scenario 014: A V0 imported recipe is refused on a robot and assigned to a person when one is present
# The fifi.cooking collection holds 2,042 described recipes (V0, RFC-0009). Every step is a legacy step that no device can execute. The dry run refuses them on any robot alone and hands every step to a person when one is present.
# Run a hub first: python hub/cookwala_hub.py --recipes examples
