I was having premature token expiration issue on hydra and it was happening after I restart the hydra.

Upon further inspection I discovered that it's due to the way coldStart is handled.

Specifically this line:
https://github.com/ory-am/hydra/blob/0baa04ebbbc62446b21824ecda7490864642ce68/internal/fosite_store_rethinkdb.go#L279

It stores the same reference over and over. It works if I assign to a temp variable first.
