1.0.0+kodimov.9: get a new guide into Kodi right after start or update

Kodi keeps its own copy of the programme guide and fetches it again only
when IPTV Simple reloads its files, on its refresh timer; restarting IPTV
Simple is not enough. After the first refresh following a Kodi start or
add-on update, if the guide changed and nothing is playing, restart IPTV
Simple with a 1-minute timer, wait for the reload, then restart it with
the hourly timer again.
