New users have a calendar without VTODO

Steps to reproduce

1. Create a new user
2. Login as him/her
3. Go to both calendar and tasks app

Expected behavior

There should be a "Personal" item in both of these apps.

Actual behaviour

There is well a "Personal" item in the calendar app but not in the task app.
This is reflected by the result of the SQL query below. In the resulting screenshot, you can see that the latest calendars do not have VTODO in their components.

SELECT id,displayname,components from oc_calendars whereid > 690;

My users are LDAP users, but the same behaviour seem to happen for local accounts.

I'm not sure this is a bug or the new default behaviour (or maybe I did change a setting without realizing it).

Additional info

Maybe this belong into core?

No source file or test is named. Start by reproducing the new-user flow and comparing the calendar records from the reported SQL query, then trace how the Personal calendar is created for the calendar and tasks apps. Done means new users have a Personal item in both apps with VTODO included in the calendar components.
