Use the correct sequence for shard replacement
Cherry-pick from Cloudant to 2.0
The call to unpack the since sequence for _changes incorrectly filtered
the value for any shard that didn't exist. This means that any shard
that was moved ended up requiring a complete rescan which is a bug. This
just sets the update sequence to the range of the shard being replaced
rather than zero.
