e502c3c515 tests: Reduce noise level in test_bitcoin output (practicalswift)

Pull request description:

  Reduce noise level in `test_bitcoin` output.

  Context: When working on the non-determinism issues in the unit tests (see #15296) I got a bit tired of the amount of noise in the `test_bitcoin` output :-)

  Before:

  ```
