Calendar name is not persistent after log out (it changes back to default name)

Steps to reproduce the bug:

1. Add a Google or a Nextcloud account in gnome-calendar
2. Activate the calendar component in the account
3. Open gnome-calendar and go to Calendar Settings
4. Choose a Google or a Nextcloud calendar
5. Change the calendar name
6. Go back, close the app and open it again
7. The new name is still there
8. Log out and log back in
9. Check the calendar name
10. It's back to the default name

The new calendar name should always be persistent and does not change to the default name.
