copies: remove redundant filtering of ping-pong renames in _chain()

We already handle the ping-pong rename case in the filtering step, so
there's very little point in doing it in the chaining loop (ping-pong
renames are very rare, so I'm not worried about the cost of adding it
and then removing it again).
