Untar makedirs fix

Avoids unnecessary directory deletion and prevents error while making new directory if that directory already exists.

If the directory removal is important, suggest:
- adding a warning to the user first. I hadn't expected anything to get deleted by this, and had pointed to a large existing directory.
- replacing os.rmdir with shutil.rmtree. os.rmdir fails on non-empty directories.
