track completion by verb does not check that the object is the specified activity id

[Getafix-hub]

The help with Track completion by verb specifies:
Moodle will look for statements where the actor is the current user, the object is the specified activity id and the verb is the one set here. If it finds a matching statement, the activity will be marked complete.

The use case is an xAPI activity which:

• contains quizzes
• uses track completion by verb using http://adlnet.gov/expapi/verbs/passed or http://adlnet.gov/expapi/verbs/failed
• generating a score and a passed / failed verb based on the number of viewed slides

In this case, multiple passed / failed statements can be generated within a single activity and the object id must be properly tested to match the desired condition.

Example:

Tincanlaunch configuration
Completion tracking: Show activity as complete when conditions are met
Activity ID: http://localhost/localcontent/HelloB
Track completion by verb: http://adlnet.gov/expapi/verbs/passed

Quiz passed statement:
verb id: http://adlnet.gov/expapi/verbs/passed
objectType: Activity
object id: http://localhost/localcontent/HelloB/quizzes/bqu2bgm3t729-kgs9lqf9hvku

Activity passed based on number of viewed slides score
verb id: http://adlnet.gov/expapi/verbs/passed
objectType: Activity
object id: http://localhost/localcontent/HelloB
