missing old certificate on fresh install

A fresh provider isn't old:

fatal: [mullet.bitmask.net]: FAILED! => {"msg": "An unhandled exception occurred while running the lookup plugin 'file'. Error was a <class 'ansible.errors.AnsibleError'>, original message: could not locate file in lookup: /home/kwadronaut/dev/leap/demo3/credentials/common/old_client_ca.crt"}

Introduced in a13d6e7f @micah given the 'old' in there, has this to do with cert migration/cycling? Is this something that's used in the wild?
