In the previous attempt [1] we improved the logic by spawning workers on the
matching target shards only. However, that wasn't enough as workers might still
reject the passed in sequence from the old node when it asserts ownership
locally on each shard.
Re-use the already existing replacement clause, where after uuid is matched,
we try harder to find the highest viable sequence. To use the unit test setup
as an example, if the moved from `node1` to `node2`, and recorded epoch
`{node2, 10}`
on the new node, then a sequence generated on `node1` before the move, for
example `12`, would rewind down to `10` only when calculated on new location on
`node2`, instead of being rewound all the way down to `0`.
