As I pointed out earlier, lilv_state_save fails here to save the state 
when it is loaded with
lilv_state_new_from_world.

It may be path issues or whatever.

Aside from that, the saved state I'm interested in, shouldn't be a 
preset in long term, it get loaded once and then 
forgotten/deleted/replaced.
Now I got it to work with lilv_state_to_string, add the missing prefixes 
and replace the uri with a empty <>.
