recursor: Move replaced cached entries to the back

When we replace an existing entry, it keeps its existing place in
the expunge queue, while new entries are inserted to the back and
hits are moved to the back.
Moving replaced entries to the back of the queue is more fair and
so probably more efficient, as it would increase the likelihood of
expunging unused expired entries from the cache.
