[FIX] website_slides: fix courses completion on user profile page

This commit fixes the courses (slide.channel) completion displayed on the user
profile page. It uses the number of completed slides instead of the percentage
of completion. This is due to the completion field having been updated
recently to store number of completed slides instead of a computed percentage
for performances reasons [1]

Commit linked to task ID 1978530 (fixes linked to internal testing).
