test_scanning_sub_dir(): - Remove try/finally - we don't need to clean up after a failed test (done in this commit to maintain indentation). Regarding symlinks: https://github.com/bitcoin/bitcoin/pull/31410#issuecomment-3554721014 Kept some symlink creation which didn't disrupt Windows cross builds to make for a smaller diff and less cumbersome code. There is some hope of eventually getting better symlink support via #34603. Co-authored-by: Ava Chow <github@achow101.com>
