When a Feedback activity is restore the "Site after submit" URL is not updated and shows "$@PAGEVIEWBYID*15463@$"

file: moodle\mod\feedback\backup\moodle2\restore_feedback_activity_task.class.php
function: define_decode_contents()

the function has:

        $contents = array();

        $contents[] = new restore_decode_content('feedback', array('intro'), 'feedback');

        $contents[] = new restore_decode_content('feedback_item', array('presentation'), 'feedback_item');

        $contents[] = new restore_decode_content('feedback_value', array('value'), 'feedback_value');

        return $contents;

the second line should include 'site_after_submit' and preferably 'page_after_submit':

$contents[] = new restore_decode_content('feedback', array('intro', 'site_after_submit', 'page_after_submit'), 'feedback');

1. Create a new course
2. Add a html page
3. Add a Feedback activity with the URL of the html page created on step 2, add some questions
4. Backup the course
5. Restore the backup file into a new course.
6. Go to the Feedback activity and submit the answers.
7. (before this fix), Moodle will show a confirmation message and a "Continue" button that will take you to "moodle/$@PAGEVIEWBYID*###@$", or
   you can go and edit the feedback activity, in URL you'll see "$@PAGEVIEWBYID*###@$"
8. Test that both situations have been fixed into properly formed URLs.
