Get the first list, clone it (a shallow clone), call clear() on the
list, then call addAll() passing the cloned list. Behind the scenes
detach() will be called but you don't have to do it.
Note this may not work perfectly with the internal PartialList impl,
which is why we're changing to FilterList.
