Currently late block reorg is disabled so this defers to `getStateAtSlotExact` This functionality diverges from `getStateAtSlotExact` with late block reorg, as sometimes the state we're wanting to use is the parent of the head. In this scenario we actually need to check the proposer head, and get the appropriate state based on that instead. The fallback given all things being equal currently is to call getStateAtSlotExact, which is basically falling back to the old functionality. - if late block reorg is disabled - if the head root can't be read - if the headRoot is the same as the root we're told to use from getProposerHead. In late block reorg case where we're using parent, we need to call `regenerateBeaconState` to apply empty slots. partially addresses Consensys#6595 Signed-off-by: Paul Harris <paul.harris@consensys.net>
