Paul Hauner e4fa7d906f Fix post-merge checkpoint sync (#3065) ... ## Issue Addressed This address an issue which was preventing checkpoint-sync. When the node starts from checkpoint sync, the head block and the finalized block are the same value. We did not respect this when sending a `forkchoiceUpdated` (fcU) call to the EL and were expecting fork choice to hold the *finalized ancestor of the head* and returning an error when it didn't. This PR uses *only fork choice* for sending fcU updates. This is actually quite nice and avoids some atomicity issues between `chain.canonical_head` and `chain.fork_choice`. Now, whenever `chain.fork_choice.get_head` returns a value we also cache the values required for the next fcU call. ## TODO - [x] ~~Blocked on #3043~~ - [x] Ensure there isn't a warn message at startup.		2022-03-10 06:05:24 +00:00
