Merge bitcoin/bitcoin#26625: test: Run mempool_packages.py with MiniWallet
fa6b402114test: Run mempool_packages.py with MiniWallet (MarcoFalke)fa448c27d2test: Return fee from MiniWallet (MarcoFalke)faec09f240test: Return chain of MiniWallet txs from MiniWallet chain method (MarcoFalke)faa12d4ccdtest: Refactor MiniWallet sign_tx (MarcoFalke)fa2d82103ftest: Return wtxid from create_self_transfer_multi (MarcoFalke) Pull request description: This allows to run the test even when no wallet is compiled in. Also, it is a lot nicer to read now. ACKs for top commit: glozow: reACKfa6b402Tree-SHA512: de0338068fd51db01d64ce270f94fd2982a63a6de597325cd1e1f11127e9075bd4aeacace0ed76d09a2db8b962b27237cf11edb4c1fe1a01134d397f8a11bd05
