In order to support a sync API with soft deletes while purging older data, we must set a reasonable window for clients to get changes before purging.
This window is set in T168990: Purge soft deletes on a regular basis
For this ticket, we need to return an error in the a client passes a date older than that window to the sync API. This error should instruct the client to do a full download as they may have missed changes if they use the sync API.

Done in https://gerrit.wikimedia.org/r/#/c/366980/. Clients get an error message with the message key readinglists-apierror-too-old (can be checked with errorformat=raw) when they ask for changes beyond the delete purging interval. The API help (via action=paraminfo) for the changedsince parameter can be used to learn what that interval is.
