replay: remove HEAD related sanity check

We want replay to be a command that can be used on the server side on any branch, not just the current one, so we are going to stop updating HEAD in a future commit. A "sanity check" that makes sure we are replaying the current branch doesn't make sense anymore. Let's remove it.
