1.0.0+kodimov.14: guide reload no longer skipped while the remote is in use; remove empty instances

- .190 on 2026-11-13: the box came on with an old epg.xml, Kodi stored it
  (no current programmes for 124 channels) and doesn't ask again for up to
  an hour. KodiMov+ wrote a new guide two minutes later, but the reload
  waited for 30 s without a key press and gave up after 10 minutes, while
  the guide was being browsed. It now waits for a 10 s pause, for as long
  as Kodi runs.
- Instances with no channel list (the "Migrated Add-on Config" Kodi makes
  when IPTV Simple is installed again) are removed once KodiMov+'s own
  instance exists.
