Without this commit: 1) read height from DB 2) add block to chain in separate thread 3) read chain for block id's and request them from peer 4) ERR in handle_response_chain_entry, peer's first block is the one that was added to the chain, which has block idx=height from step 1. This commit reads the chain for height and highest block id's in one go while holding the m_blockchain_lock to avoid the race. (cherry picked from commit d8d3cf97300480b9d3942c667978dd4860b76feb)
