Fix applyAdjustmentsFromAssistants

Issue: r.applyAdjustments() updates the NotificationRecord from the
       adjustments, which makes handleRankingSort failed to diff
       the NotificationRecord properly as it is already updated

Solution: Only update the importance bit in applyAdjustmentsFromAssistants

Test: runtest systemui-notification
Test: Posted a notification, observe smart replies. Reboot, still
      seeing the smart replies.
