Title: Protect against cache_hits on non-existant entries

This can happen if we load a shard set from the cache and then eject the
shards before processing the cache_hit '$gen_cast' message. Instead of
trying to be fancy and reinserting the shards into the cache directly we
just rely on the fact that they'll be reinserted normally on the next
request.
