Looks like this first started showing up with bug 1468812 which makes some sense I guess. I think this situation can only happen if there is a broken symbolic link, so in that case let's just remove it to be safe.

I have no idea how this could still be happening :/. Unless the "test_root" dir is somehow being created between the os.path.exists() check and os.symlink()..
