client_name, token_username not being written to config.json

[airswing]

Describe the bug
In 1.0.0 (latest image), after creating a client using tapis auth init, looking at the config.json, client_name and token_username are null.

Expected behavior
In config.json, after a client is created, client_name should be set to the string displayed in the CLI. Not sure if token_username should also be set, but I'm pointing it out because it too is null.
