Merge #14855: test: Correct ineffectual WithOrVersion from transactions_tests

75778a0 test: Correct ineffectual WithOrVersion from transactions_tests (Ben Woosley)

Pull request description:

  `WithOrVersion` uses `|` to combine the versions, and `|` with 0 is a no-op.

  NicolasDorier / sipa do you recall why the version is being overridden here?
