[PATCH] LocalStatus.py: Fix getfolders()

[Sebastian Spaeth]

This code was unused and broken. It is still unused but this commit
fixes it. (We should retain the method in case we ever start calling
getfolders() on LocalStatus.

This code was unused, but Vladimir's folder creation patch were
relying on this code being used, so this fix should go into 'next'.

Vladimir, here you go. I hope this will help with the folder
creation patches.
