Each keyserver can have different connection status and modifying this logic to take this into account could be complicated. Instead, we can simply check if we're connected to network at all and try to load more entries. If, for some reason, some keyservers won't receive this update, CalendarQueryHandler should fix it later, based on currentCalendarQuery which is updated on updateCalendarQueryActionTypes.started.
