1.0.0+kodimov.6: keep refreshing the programme guide on boxes set up with kodimov.1

kodimov.1 shipped the automatic guide export off. Kodi stored that value,
so the later default of on never applied and only the channel list was
refreshed; the 2-day guide ran out. Rename the setting so the new default
applies, and turn it on from the one-tap TV guide setup.
