[Geary] special folders not detected are created on server by Geary

[Federico Bruni <fede inventati org>]

Hi all

Two days ago I've cleared my Geary configuration files and started from 
scratch with new databases for each account.
I'm not sure if it's related,  but since then some special folders are 
not detected by Geary. I also found out that Geary creates special 
folders on the server if the server doesn't report special-use/xlist. 
See here:

Does it mean that servers are not working correctly all of a sudden?
I'm using the same ports and configuration as in the past...

And if Geary is supposed to create a special folder if missing on the 
server, then I guess it does not work always. See:
