bf77fea test: fix incorrect named args in txpackage tests (fanquake)

Pull request description:

  Final non-scripted-diff commit split from #24661.

  Could be tested with: `./autogen.sh && ./configure CC=clang-12 CXX=clang++-12 && make clean && bear make -j9 && ( cd ./src/ && run-clang-tidy-12 -j9 )`.

  Motivation:
  > Incorrect named args are source of bugs, like bitcoin/bitcoin#22979.

  > To allow them being checked by clang-tidy, use a format it can understand.
