    weather-service: Set contact_info to DOAP file URL
    
    Currently, GNOME Calendar does not set up the contact_info needed in
    libgweather 40 API. This leads to the following assertion, and no
    weather forecast info being shown in Calendar:
    
    `gweather_info_update: assertion 'info->contact_info != NULL' failed.`
    
    To fix the assertion, set the URL to the DOAP file on the master branch.
    GNOME Weather does the same, see:
