NATS subject incorrectly rendered when Raspberry Pi hostname is "printnanny"

[leigh-johnson]

Describe the bug

I'm seeing auth failures with the following error:

Jan 26 16:21:20 printnanny printnanny-nats[1070]: [2023-01-26T21:21:20Z ERROR printnanny_nats::subscriber] Error deserializing NATS message: NATS message handler not implemented for subject pattern pi.{pi_id}.settings.{pi_id}.cloud.auth

This subject pattern should be pi.{pi_id}.settings.printnanny.cloud.auth - but printnanny is getting replaced multiple times if the hostname is also printnanny

Verified this is now fixed - I was able to add a Raspberry Pi with hostname printnanny to my growing collection:
