Use www.mncvision.id as TV guide source.

Guide for mncvision.id expects to be POST request. The first POST request
indeed routed to https://mncvision.id/schedule/table, but this site will
then redirect it to https://www.mncvision.id/schedule/table. The redirection
will use GET request, so the schedule POST data will never be received
by the site.
