> When space.before_replace trigger modifies the result of a remote
> operation, we clear the request header so that it gets rebuilt on
> commit. This is incorrect, because as a result we don't bump the
> master's component of the replica's vclock, which leads to the request
> being applied again when the replica reconnects. The issue manifests
> itself in sporadic replication/before_replace test failures.
> Fix it by updating the request header rather than clearing it so that
> replica id and lsn get preserved.
> Closes #3722

OK to push.
