Title:
  Shared access with users produces a warning in 19.10 when search
  results count = 0

Status in Mahara:
  Fix Released
Status in Mahara 19.04 series:
  Fix Released
Status in Mahara 19.10 series:
  Fix Released

Bug description:
  The code currently in 19.10 to share access with 'Users' will produce
  a warning when the search count is 0, i.e a site that has no current
  users.  It's possible there are other ways to return a User search
  count of 0 but this is the most reliable for testing purposes.

  The warning message is:
  [WAR] c4 (view/access.json.php:60) Invalid argument supplied for foreach()

  To reproduce:
  1. On a fresh install of Mahara 19.10 codebase with no users, create a page.
  2. Navigate to "Share" and select to edit share access for the new page
  3. Select "User" from dropdown box and scroll on the drop down to select a User (it will say No results found)
  4. Refresh the page
  Expected results:
  Page displays no warnings
  Actual results:
  Page displays with a warning message

  This is happening in 19.10 (possibly a fix needs to be applied to
  earlier versions of the code).  This issue didn't affect code after
  19.10.
