Don't try to assign registered role on global tenant

[cjcolvar]

On a fresh checkout of hyku, I was not able to register a user on the global tenant because the
before_create callback errored when trying to add the registered role
due to a validation error on the role: Resource type is not included in the list
This was not caught in the tests because there wasn't a check that the
user actually got created.

guess I'll cross this off my list of things to get committed back from last week https://share.getcloudapp.com/RBul5JrP =-D

Also, i didn't see it before, but I think its the line feed in the original that is the problem. the unless would have a nil after it and the next line would evaluate true or false but not return to anything. Your way is cleaner and (obv) less error prone.
