Public group with allow submissions ticked causes error (Bug #1310761)

This is due to the dummy 'root' user having the same id, which is 0, as
an anonymous user.

Needed to not include the dummy 'root' profile page in the get views
and collections db call.

Title:
  public group and allow submissions problem

Status in Mahara ePortfolio:
  In Progress

Bug description:
  When making public a group that has Allow submissions also ticked we
  get this error:

  [WAR] b7 (lib/user.php:1678) profile_url called with no user id
  Call stack (most recent first):

      profile_url(object(stdClass), false) at /home/robertl/htdocs/mahara-testing/mahara/htdocs/lib/view.php:4602

      PluginBlocktypeGroupViews::render_instance(object(BlockInstance)) at Unknown:0

  The problem stems from an anonymous user viewing the public group
  being assigned the same id, which is zero, as the structural dummy
  user. That dummy user has a default 'profile' page and this is causing
  the problems.
