    [CalDAV/CardDAV] Can add component to local cache with incomplete info
    
    When a component/contact is loaded from the server when it's not part
    of the local cache (which can happen for example with meeting invitations),
    then the fetched object was stored without the href in the local cache,
    which made it impossible to edit the object later (it resulted
    in an "Invalid Object" error).
