Related #4587

The mutation testing highlighted there might be missing unit tests for load_block_parent_info but there needs to be created a default for NakamotoNodeError, NakamotoBlock and ParentStacksBlockInfo to check it.

The steps for making sure the load_block_parent_info function has its possible outcomes caught are:

• [ ] create default for BlockBuilderSettings
• [ ] remove the skip header #[cfg_attr(test, mutants::skip)]
• [ ] check if mutation tests are caught for these cases:
  • [ ] run

  RUST_BACKTRACE=1 BITCOIND_TEST=1 cargo mutants -vV -F "replace BlockMinerThread::load_block_parent_info" -E ": replace .{1,2} with .{1,2} in " --baseline=skip --test-tool=nextest -- --run-ignored all --no-fail-fast --test-threads 1
  

  • [ ] Ok(Default::default())
• [ ] create tests if they aren't caught

---

Exactly the same flow for:

• [ ] mine_block

 RUST_BACKTRACE=1 BITCOIND_TEST=1 cargo mutants -vV -F "replace BlockMinerThread::mine_block" -E ": replace .{1,2} with .{1,2} in " --baseline=skip --test-tool=nextest -- --run-ignored all --no-fail-fast --test-threads 1

• [ ] lookup

  RUST_BACKTRACE=1 BITCOIND_TEST=1 cargo mutants -vV -F "replace ParentStacksBlockInfo::lookup" -E ": replace .{1,2} with .{1,2} in " --baseline=skip --test-tool=nextest -- --run-ignored all --no-fail-fast --test-threads 1
