Bugfix on Stanford CME Templates

* The open source version of the Stanford CME template has drifted since
  last checkpoint; this brings it up to date.

* This is a stopgap fix to help Stanford out; now that v3_dynamic is
  landed, it should live exclusively in Stanford's working fork and be
  removed from upstream. That is work for a future branch.

@stvstnfrd and @jbau this is what we need to be able to deploy cme to prod with the open source certs repo.
This just normalizes to the way it's being done in v3_dynamic, which is more readable and less tied to s3.
