Actually check if roles are set

In the helper functions to check if roles are set and if not add the
role and return the id we weren't actually checking if the role was set.
The reason for this was we grepped for name values while outputing only
uuid values with OSC. Fix for this is straightforward, we just add the
--role argument to OSC which will filter for us then we don't have to
use a grep on the wrong value type.
