Unable to access archive_permission for archive when not logged in

[Łukasz Zemczak]

When running as an anonymous user, accessing archive_permissions for a distribution's main_archive does not work.

>>> perms = lp.distributions['ubuntu'].main_archive.getAllPermissions()
>>> len(perms)
761
>>> perms[0]
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/lazr/restfulclient/resource.py", line 854, in __getitem__
    raise IndexError("list index out of range")
IndexError: list index out of range

The same operation works correctly when ran as an user.
