Merge #20998: test: Fix BlockToJsonVerbose benchmark

7487bc9 Fix BlockToJsonVerbose benchmark (Martin Ankerl)

Pull request description:

  Currently it was not possible to run just the BlockToJsonVerbose benchmark because it did not set up everything it needed, running `bench_bitcoin -filter=BlockToJsonVerbose` caused this assert to fail:

  ```
  bench_bitcoin: chainparams.cpp:506: const CChainParams& Params(): Assertion `globalChainParams' failed.
  ```

  Initializing TestingSetup fixes this.
