GOA-configured Nextcloud account not appearing
When setting up a Nextcloud account with GOA for the first time, it doesn't appear in Contacts (and apparently, the calendar isn't synced either).
It seems Contacts doesn't get the source from EDS, as the only one found is the local addressbook:
gnome-contacts-DEBUG: 17:39:52.539: contacts-accounts-list.vala:74: Found 1 EDS stores
This works as expected using version 3.34.3 and 3.35.92, but is broken in 3.36.0 and later. If a Nextcloud account is already configured and used prior to upgrading to 3.36.*, it can still be used. However, any account created with these latest versions won't be usable from Contacts.
