Folio: DELETE_OLDEST_FILE on already disconnected device

[dkrefft]

Hi,

I'm using tuhi-dev (main branch) with my Wacom Folio to sync the drawings. Everything works so far until the point when the drawing should be deleted. The the following error occurs.

18:26:47 DEBUG: tuhi: Drawing received

If that helps these are the current device information

If you have any changes in code you think it is worth a try. Just drop me a message if I can support here. :)
