Always print roles with list-roles

[blackliner]

We use list-roles in a wraper script to gather the available okta accounts. I think skipping the output is not properly placed in this function call, because the intention of it is to actually list them, not do any shortcuts. Hence I removed this check for only one list, as I do not see why it should behave differently in this case.
