LGTM.
Note that with this PR parent beacon root will always be 0x00.000. But IMO it's still better than the undefined behavior of calling a contract that doesn't exist.
For a more meaningful result we should either allow users to set a custom root via API (similar to how we have to withdrawals), or actually produce some block in simulated beacon. I'm inclined to kick this can down the road :)
