* Unify autoIS/send_smth functions * Rename autoix-mempool.py -> autois-mempool.py * Make sure create_raw_trx produces expected results * Make sure sender has enough inputs and nodes are synced before starting the actual test * Mine one block to clean mempool up * 2 blocks is enough for IS on regtest This also unifies it across different IS tests * Allow wait_for_instantlock to be called on any node, not only on the one that has the tx in the wallet * No need to query for tx this often in wait_for_instantlock * Rename create_raw_trx -> create_raw_tx * Fund sender with a single TX instead of 30
