User registration via the backend does not consistently populate the org id
field. Fix this.
Chris, I think what's going on here is the org_id field will not be filled in
when we are creating a new user that isn't to be added to an exisiting org; it
should get its own new org. Does this make sense? What should happen in that case?
From what Chris tells me, this will require a change in the userservice code. So
it may or may not require a change on our part. Moving to 505-triage.
Since we're disabling new user creation in rhn_register, this won't be a problem
