[Labs-l] No nova credentials... bug fixed for most use cases

[Ryan Lane]

Follow-up on this. Seems I had a minor bug in the deployed code which was
causing the credentials bug to still occur. I tracked it down and fixed it
in change Iea6b565c. Once deployed in production my credentials suddenly
reappeared, which indicates this should indeed solve the problem
(hopefully permanently).
