Saving geometry to xyz file is confusing

[Jakob Jakobson]

Hi,

if you want so save a molecule to a xyz-file, it get's confusing as the file does not get saved when you click save but when you close the window by clicking cancel.

To reproduce this behaviour:
1. install avogadro (version 1.93.0-1) on ubuntu 20.04
2. draw a molecule
3. try saving geometry to xyz file by File -> Export -> Molecule -> <filename.xyz> -> save
   -> the window reopens (don't close it for the moment)
4. check the folder for the file <filename.xyz>
   -> on my pc, I can't find it
5. go back to avogadro and click "cancel" in the export window
   -> window closes and you are back in the main screen
6. check the folder for the file <filename.xyz>
  -> on my pc, now it is there
