Default wine prefixes folder can be left empty

[arielj]

Describe the bug

When in the General settings, the Set Folder for new Wine Prefixes setting can be left blank, leading to problems installing games.

This is a problem because a user may delete it by mistake and we run no validations and no fallback.

This is the log deleting the path:

Steps to reproduce

1. Go to Settings
2. Leave the Set Folder for new Wine Prefixes option completely empty
3. Try to install a game (the installation folder will by just /theGame which is most likely invalid for installation)

Expected behavior

We should warn the user that they left an empty value there and what the default original value was, so they can leave it empty if they know what they are doing or revert it back to the original it if was a mistake.
