[test] make submit optional in CreateValidMempoolTransaction

This allows us to easily create transaction chains for package validation. We don't test_accept if submit=false because we want to be able to make transactions that wouldn't pass ATMP (i.e. a child transaction in a package would fail due to missing inputs).
