The tutorials function simply does not work. The "Default" tutorial should, I believe, populate the "tutorials" table, which is empty. I believe this results in the bug seen in 14786. Clicking on the pulldown just produces a reload. There is no administrative menu for the tutorial function. The "tutorial" admin verb redirects to a broken link. I believe there are several ROOT CAUSES here.

1. controllers/AdminController.php: getActionClasses() should return a key of 'tutorials' and not 'tutorial'

2. ./helpers/update/updatedb_helper.php:
   //Reset Surveymenues and tutorials to fix translation issues
   if ($iOldDBVersion < 346) {
   $oTransaction = $oDB->beginTransaction();
   createSurveyMenuTable($oDB);
   $oDB->createCommand()->truncateTable('{{tutorials}}');
   $oDB->createCommand()->truncateTable('{{tutorial_entries}}');
   $oDB->createCommand()->truncateTable('{{tutorial_entry_relation}}');
   $oDB->createCommand()->update('{{settings_global}}', ['stg_value'=>346], "stg_name='DBVersion'");
   $oTransaction->commit();
   }

or in 337...

The table is truncated. Where is it supposed to be populated? It never worked.
