Title:
  Error when adding LTI connection: 'component' not available

Status in Mahara:
  Fix Committed

Bug description:
  Mahara master:

  When I try to add 'LTI integration' to 'No institution', I get the
  following error message:

  [WAR] 59 (webservice/admin/oauthv1sregister.php:772) Trying to get property 'component' of non-object
  Call stack (most recent first):

  ------------

  It is not a problem when trying to add 'LTI integration' to an
  institution.

  It is also not a problem when adding 'LTI integration' to 'No
  institution' when an institution exists.

  To replicate:

  1. Make sure you do not have any institutions on the site and only 'No institution'.
  2. Go to Admin menu -> Web services -> External apps.
  3. Create an 'LTI integration' connection for 'No institution'.
  Expected result: The connection is created.
  Actual result: The connection is created but with the error message above.

  To test once fixed:

  a) The above scenario
  b) The scenario but with an institution
  c) The scenario but with 'No institution' when an institution is available
