[Bug]: The placeholder folder in ~/.var is not being deleted after I delete a bottle created in a custom directory

[moonlitpath]

Describe the bug

When I create a bottle in a custom directory, Bottles also creates a folder with the same name in ~/.var/app/com.usebottles.bottles/data/bottles/bottles/, which contains a placeholder.yml file. When I delete this bottle, Bottles removes placeholder.yml; however, the folder it was in is not deleted. This prevents the creation of bottles with the same name in the future because Bottles shows an error: "Unable to create Bottle. Failed to create placeholder directory/file."

To Reproduce

1. Create a bottle, choose any Bottle Directory other than "Default" (give Bottles appropriate permissions if necessary)
2. In the bottle's details, click "Delete Bottle" from the hamburger menu
3. Create a bottle with the same name in the same directory

Haha this is amazing, I came here to report the exact same bug. I am using the latest Bottles Flatpak and saw the exact same issue:

• I created this bottle: /mnt/media_storage/Games/Bottles/Prefixes/Star-Citizen
• ~/.var/app/com.usebottles.bottles/data/bottles/bottles/Star-Citizen was also created. It contains a placeholder file with the full path to the actual wineprefix location.
• I deleted the custom bottle inside Bottles GUI because I made a mistake with the path.
• Tried to make another and got the error about (ERROR) Failed to create placeholder directory/file at: /home/x/.var/app/com.usebottles.bottles/data/bottles/bottles/Star-Citizen
• Saw that the directory existed. So I deleted it manually and tried again. Now it worked.

So yeah there's an incomplete cleanup when deleting bottles.
