Backup report no longer links to the individual course backup summaries (backport of MDL-30937)

Test 1 Visit 'Site administration' > 'Development' > 'Debugging' and set 'Debug messages' to 'NONE: Do not show any errors or warnings'. Create a few courses. Visit 'Courses' > 'Backups' > 'Automated backup setup'. Change the setting (if it isn't already) 'Active' to 'Enabled' and save. Run the script php admin/cli/automated_backups.php a few times. Turn debugging developer back on. Run the script php admin/cli/automated_backups.php a few times. Visit 'Site administration' > 'Reports' > 'Backups'. There should be a list of courses you created with their backup details. Click on the icon next to each course and browse the backups created and ensure the steps are correct - for the backups where there were no logs recorded (when debugging was turned off) confirm you get a message telling you that there are no logs for that backup. Test 2 Make sure debugging is turned on. Add a forum to a course. Edit the file mod/forum/backup/moodle2/backup_forum_stepslib.php. Add an exit(); in the middle of the function define_structure(). Run the script php admin/cli/automated_backups.php. Visit 'Site administration' > 'Reports' > 'Backups'. Click on the icon next to a course with a forum. The backup status should read 'Unfinished'.
