[gnome-calendar/mcatanzaro/#397] week-header: Remove internal weather service

[Georges Basile Stavracas Neto <gbsneto src gnome org>]

commit 3ed9669c6e50afffe4a2aca448e46cfdf92b6722
Author: Michael Catanzaro <mcatanzaro igalia com>

    week-header: Remove internal weather service
    
    self->weather_service was only partially removed in 01fdf79e6a,
    leading to a guaranteed crash when the weather is updated because
    self->weather_service is now always NULL.
    
    Fixes #397
