 If there is not a block from the proposer for `state.slot`, a "skip block" is inserted into the beacon chain:
 * Let `block` be a skip block defined by `get_skip_block(state.slot, parent, parent_hash)`.
 
-Set `state.latest_block_hashes` to `state.latest_block_hashes + [parent_hash]`. (The output of `get_block_hash` should not change, except that it will no longer throw for `state.slot - 1`.)
