I'd messed up a rebase in my previous iteration, causing `weakly_canonical` to reappear, but not trigger a test failure. These two functions behave similarly when the argument is a path that points to a broken symlink. `weakly_canonical` would not resolve it because the target doesn't exist, and `makeParentCanonical` would not resolve it, because it never resolves the final path element. This new test case now also tests a valid symlink, "differentiating" the two.
