"Call to undefined function artefact_instance_from_id()" when deleting a profile icon

[Aaron Wells]

To replicate:

1. Upload a profile icon
2. On the "Content -> Profile pictures" page, tick the box next to the uploaded profile icon.
3. Press the "delete" button

Expected result: icon is deleted
Actual result: Fatal crash with this error:

( ! ) Fatal error: Call to undefined function artefact_instance_from_id() in /home/aaronw/www/mahara/htdocs/artefact/file/profileicons.php on line 317
