[gnome-contacts] Search very long
When using Gnome Contacts linked to a Nextcloud account, containing around 1000 contacts:
- first display of the list of contacts takes around 15s
- search for a contact is very long (application freezes for 5s after typing the first letter in the search bar, and a bit less after each next letter).
When starting the application from the terminal, the following warning is logged:
Error preparing Backend 'telephathy': The name org.freedesktop.Telephathy.AccountManager was not provided by any .services files
