fix: Fix clearing of one-time-completion manual self-report assessments from notification (M2-8144, M2-8160)

📝 Description

🔗 Jira Ticket M2-8144
🔗 Jira Ticket M2-8160

When tapping a notification to start a manual self-report assessment, the targetSubjectId was not being normalized to null as is needed to identify self-reports elsewhere in the app. Fixed this at the NotificationBuilder step.

🪤 Peer Testing

Preconditions:

• User has an applet with activity that is set to Auto-assign: false and has a manual self-report assignment
• Add new scheduled event for activity:
  • Repeats daily
  • Notification = in the next 5 minutes (or however long it takes you to refresh and force-close the applet)

Steps to reproduce:

Online mode:

1. Refresh the applets list to ensure it has the latest updates from the activity (including the notification setting)
2. Kill (close) the app
3. Wait for the notification time
4. Start the Activity by tapping the notification
5. Complete activity
   Expected outcome: Activity is hidden from the list of activities.

Offline mode:

1. Refresh the applets list to ensure it has the latest updates from the activity (including the notification setting)
2. Kill (close) the app
3. Take internet offline
4. Wait for the notification time
5. Start the Activity by tapping the notification
6. Complete activity
   Expected outcome: Activity is hidden from the list of activities.
