core_completion_get_activities_completion_status was not returning
completion information for users with the teacher role only (when it
wasn’t a role allowed to track completion).
- Icon generation logic moved to the course renderer.
- Web service should return the completion info only, not HTML.
- JS modified to handle icon rendering in relevant cases.
Changes:
- Activities with auto completion and a completion status overridden to
COMPLETION_COMPLETE are no longer processed by normal completion
triggers.
- All activities can still be completed by students when their
completion status has been overridden to COMPLETION_INCOMPLETE, via
either auto or manual triggers.
- Completion unit tests updated
