Title:
  Publicaly viewable group with submissions

Status in Mahara:
  Fix Committed

Bug description:
  Mahara: 17.10.2 (2017092611)
  OS: Linux 16.04 (php 7)
  DB: Postgres
  Browser: FF && Chrome (any)

  
  When a group is created with the following settings:

  * Allow submissions = Yes
  * Publicly viewable group = Yes

  When a user who is not logged in tries to view this group (i.e.
  because they know the URL), they get the following error:

  [WAR] 75 (lib/user.php:1943) Undefined variable: id

  Because the group is submittable, the application is trying to
  retrieve a list of submitted pages/collections to this group.

  A check is required to ensure the user is logged in before it
  retrieves this data.
