if we try to "rho profile edit" a profile that doesnt exist:

Traceback (most recent call last):
File "/home/adrian/src/rho/bin/rho", line 22, in

A trace back does not occur, but we incorrectly state:

$ rho profile edit --name=not_a_profile --hosts 192.168.50.[10:12] --auth test
Auths do not exist.

Current control flow sets both profile and auth to does not exist. Checks for profile and if found checks for auth. If profile doesn't exist it doesn't change the state of auth even if it does exist. Problem is it prints info about Auth does not exist first. Need to update error information flow.
