Assert height to hash in contains block

[almogdepaz]

Purpose:

use the height to hash when checking for "contains_block" block that way we always get the relevant block for the chain being validated
and create better separation between Augmentedblockchain and the underlining blockchain.

Current Behavior:

we call contains block that checks the block_record cache, this will return true if the block is in the cache regardless if is relevant to the chain

New Behavior:

contains_block will check the height_to_hash, the AugmentedBlockchain will return true for blocks that are in the fork and the underlining will return true only for blocks that are in the current chain, as we switch to the fork blocks in the underlying blockchain once the new blocks pass the height of the old fork peak we clean the height_to_hash blocks from the augmented (since now they are present in the underlying height_to_hash)

given that contains_block() is non-trivial now, it would probably be good to have a unit test

[arvidn]

looks good, just a few comments/questions
