[Bug]: Savefiles are gone after changing runner from Soda 7.0-9 to 9.0-1

[Antoniossss]

Describe the bug

I have switched my working bottle runner from soda-7.0-2 to soda-9.0-1 and this made savefiles for all of my games gone. Every game launches as it would be launched for the first time etc. Switching back to 7.0-2 fixes the issue like nothing happened. Switching to soda-8.0-2 works fine on the other hands. Games runs smoothly and all savefiles are there
Whats happening?

To Reproduce

1. Have bottle configured with soda-8.0-2
2. Play something, create save file
3. Switch runner to soda-9.0-1
4. Try to play again - previously saved game is gone, game looks like freshly installed.

This sounds like it might be because of #73
