clean overflow blocks moved to unfinished block cache on reset chain

[almogdepaz]

Purpose:

clean redundant blocks from overflow cache

Current Behavior:

when we call reset_chain we reset the unfinished block cache moving relevant blocks that can be infused from the overflow cache to the unfinished cache, we dont remove the overflow blocks we moved from the overflow cache creating redundant duplication

New Behavior:

remove the blocks that where moved to the unfinished block cache
