Fix error when overwriting a bad symbolic link installing an nbextension...

Fix error when overwriting a bad symbolic link installing an nbextension The unit test fails before this fix and works after this fix. Basically, if the already-installed symlink is a bad link, .exists() returns False (so the existing link is not removed), while .lexists() will return True (so the existing link is removed).
