Fix: Invalid event functions defined

When the student clicked "Submit and finalise" the following message
appeared when debugging was enabled:

  Invalid event functions defined in
  \mod_coursework\event\assessable_uploaded

This event class has now been updated to reflect changes in Moodle 4.2
(see MDL-52805).
