The test was using a tx with a parent UTXO that was randomly chosen from a very limited set of 4 recently matured coinbase UTXOs, so the likelihood of making the parent UTXO immature by reorg-ing two blocks prior to the tx, making the tx itself invalid, was high (20%). Fix this by making sure the parent tx UTXO always remains mature after the reorg. Note that mining the additional 100 blocks and waiting for fulcrum and Electrum ABC to catch up only adds about 1 second to the test duration.
