Subject: core: clean TODOs (#539)

* core: fix block timestamp (#529)

* Remove TODO

dMoment is still required when the block timestamp of
the genesis block is still need to be verified.

* Refine timestamp when preparing blocks
* Add timestamp checking in sanity check
* Revert code to patch position when preparing
* Remove TODOs that seems meaningless now
* Remove TODOs related to refactoring

* core: remove finalization (#531)

- Remove types.FinalizationResult, randomness
  field would be moved to `types.Block` directly.
- Add a placeholder for types.Block.Randomness
  field for blocks proposed from
  round < DKGDelayRound. (refer to core.NoRand)
- Make the height of the genesis block starts
  from 1. (refer to types.GenesisHeight)
- The fullnode's behavior of
  core.Governance.GetRoundHeight is (assume
  round-length is 100):
  - round: 0 -> 0 (we need to workaround this)
  - round: 1 -> 101
  - round: 2 -> 201
  - test.Governance already simulate this
    behavior, and the workaround is wrapped at
    utils.GetRoundHeight.

* core: fix issues (#536)

fixing code in these condition:
- assigning position without initializing them
  and expected it's for genesis
- compare height with 0
