- TestVerifyBlkDescendant
- Test_verifyBlkFinalizedSlot_invalidBlock
- TestChainService_SaveHeadNoDB

* update best justified from genesis

* deal with nil head on saveHead

* initialize prev justified checkpoint

* update finalization correctly

* update finalization logic

* update finalization logic

* track the wall clock on forkchoice spectests

* export copies of checkpoints from blockchain package

* do not use forkchoice's head on HeadRoot

* Remove debug remain

Co-authored-by: terencechain <terence@prysmaticlabs.com>

* terence's review

* add forkchoice types deps

* wtf

* debugging

* init-sync: update justified and finalized checkpoints on db

* call updateFinalized instead of only DB

* remove debug symbols

* safe copy headroot
