Personal calendar cannot be removed

[xaltube]

Steps to reproduce

1. Go to Calendar App
2. Delete the "Personal" calendar
3. Refresh the view
4. "Personal" calendar appears again

Expected behavior

Once a Calendar is deleted for a user it should not be automatically created again.

Actual behaviour

When the default "Personal" calendar is deleted, it is automatically re-created.

As I cannot define a default calendar other than the personal one, creating a new appointment goes by default to this one instead of the shared one that I want my users to use as default.

I don't mind having a Personal calendar, but I would like to be able to set a default calendar for new events.

If I get an invitation outside my NextCloud instance, I can pick which calendar to use. But if it's from another NextCloud user, it gets dropped on my personal calendar, and I can no longer move it to my work calendar... this did work before I upgraded the Calendar app to 4.7.4...

It is indeed good idea to have a personal calendar, but it should be on the site Admin side to decide if this is created by default for any new user, and also if it is mandatory and therefore should be automatically created back if the user removes it, or even t prevent it from being deleted.
