No activity shown for user creating a systemtag

Description

There is no activity shown when a user creates a tag using an API in that user's activity page.
But, this activity is shown in admin's activity page.

Although if an admin creates a system tag using the same API then this activity is listed in admin's activity page.

Steps to reproduce

1. As a normal user make a curl command
   curl -u hero:1234 \ -X POST \ -H "Content-Type: application/json" \ --data-binary '{"name":"loremnew","userVisible":"1","userAssignable":"1","userEditable":"1"}' \ "http://localhost/core/remote.php/dav/systemtags"

2. Go to the same user's activity page and find out there is no such activity

3. Go to the admin's activity page and see other user's activity.
   

4. Also as admin make curl
   curl -u admin:admin \ -X POST \ -H "Content-Type: application/json" \ --data-binary '{"name":"loremnewnew","userVisible":"1","userAssignable":"1","userEditable":"1"}' \ "http://localhost/core/remote.php/dav/systemtags"

5. Go to admin's activity page and see the activity listed there.
   

Expected behavior

User should an activity of him creating a system tag.
