Problem with relative targetPath in 0.4.8

[ajssd]

Extracting to a relative directory worked in 0.4.7, but now in 0.4.8 it causes an error.

var zip = new AdmZip("../lib/" + fileName);
zip.extractAllTo("../lib/" + dirName, true);

Looks like the code throwing the error is

if (!pth.resolve(targetPath, entryName).startsWith(targetPath)) {
  throw Utils.Errors.INVALID_FILENAME + ": " + entryName;
}

What's happening is that pth.resolve() is returning a /full/path/to/the/entry, but it does not start with 'targetPath' since 'targetPath' is relative as shown above.
