We currently try to get the recently finalized head tipset:

https://github.com/filecoin-project/go-f3/blob/5fc96af6b505faa6cc254bcf1de772378edf6aeb/host.go#L349-L354

However, if it's on a fork, we may not have it. Instead, we should get our current head and use the finalized head's epoch, our head epoch, our head timestamp, and the EC period to compute the correct delay.
