```
Fix divergence bug when peer reconnects reusing a prior replica id

We forgot to observe the footprint of the reconnecting replica's prior
undos into the local clock. This could cause the replica to generate
edits with a version strictly smaller than what other peers may have
observed. As such, those peers would think they had already seen those
edits and skip them.
