...try_get_chain_pos In try_get_chain_pos, when we notice that a transaction is not included in the best chain, we check the transactions in mempool to find conflicting ones, and decide based on that if our transaction is still in mempool or has been dropped. This commit adds a check for transactions conflicting with the unconfirmed ancestors of our tx. Co-authored-by: Wei Chen <wzc110@gmail.com>
