Description

Trying to copy a test project from pirca to tordo.

First, the project contained only collections and container requests. The collections were copied, container requests ignored (as expected).

# on shell.tordo
$ arv-copy pirca-j7d0g-bbu5p6jsjjfokta

Then, I copied a registered workflow into the project, and tried to copy it again:

$ arv-copy pirca-j7d0g-bbu5p6jsjjfokta
Traceback (most recent call last):

    return self._stream

During handling of the above exception, another exception occurred:

    raise YAMLStreamError('input stream needs to specified')
ruamel.yaml.error.YAMLStreamError: input stream needs to specified

Interestingly, this doesn't seem to happen all the time:
