Sync fails if deployment is synced on another date than the day it is deployed

[aanil]

We noticed a number of errors when syncing 240528.7d230cd-bimonthly on May 29 that started with
Skipped '/vulpes/ngi/staging/240529.7d230cd-bimonthly' path due to this access issue: '/vulpes/ngi/staging/240529.7d230cd-bimonthly' is not a directory
This was a deployment that did not exist.

The syncing worked when the deploy_date in tasks/set-paths.yml was changed to the date the deployment was done.
