 #!CommitTicketReference repository=""
 Remove negative Age assertion and truncate to zero instead.

 The Age reported on response objects is calculated from the last
 request timestamp taken. For a cache hit that hasn't been on a
 waitinglist, that will be the Start timestamp. This opens a race where
 the requests' last timestamp could be before the objects t_origin.

 Truncate the Age to zero rather than assert in that case.

 Fixes: #1486
