Extract all compressed files inside a folder

### Configuration
- Keka version: [e.g. 1.2.0 (4179)]
- macOS version: [e.g. 10.15.7]

### Describe the bug
Extracting rar files in folders / subfolders not possible.

### To Reproduce
I've got a folder with rar files in it, some rar files even in subfolders.
When trying to extract via context menu (use keka to extract) or via normal keka screen (drop to extract) I always get > "Extraction failed". Do I pick every rar archive one by one, it works fine.

### Expected behavior
I would like to extract files in a folder at once by dropping the folder icon (it used to work before....).
