    Description

      If user is enrolled in courses from other host (host 2) by mnet, and block "Courses" is activated in actual host (host 1), error shown : 'Can not find data record in database table course'.

      Steps to reproduce:

      1. Enrol user (user A) in course from other host (host 2) by mnet
      2. Activate block "Courses" in Home of host 1
      3. Access with user A in host 1

      Error shown : 'Can not find data record in database table course'.

      This is because in file:

      blocks/course_list/block_course_list.php, in function get_remote_courses()

      		 
      $coursecontext = context_course::instance($course->id);

      That's defined in the file :

      lib/accesslib.php

      		 
      ...
      		 
      if (!$record = $DB->get_record('context', array('contextlevel'=>CONTEXT_COURSE, 'instanceid'=>$instanceid))) {
      		 
                    if ($course = $DB->get_record('course', array('id'=>$instanceid), 'id,category', $strictness)) {
      		 
      ...

      but $course->id not in table 'course' because it is an MNet course.

      I think solution is commented:

      blocks/course_list/block_course_list.php, get_remote_courses()

      		 
      $coursecontext = context_course::instance($course->id);
