Validate config.json on launch

[Araxeus]

Currently, if config.json is corrupted somehow, the app just won't launch / shows a white window / error, which makes it very hard for users to fix

error thrown from https://github.com/th-ch/youtube-music/blob/23058729f3965deb0bff9b638feb5d419da6e913/config/store.js#L79-L83

To fix this I propose either:

1. - clearInvalidConfig: false,
   + clearInvalidConfig: true,
   

2. wrap the Store constructor inside a try...catch, on catch prompt the user:

   Error in config.json 
   "SyntaxError: Unexpected string in JSON at position 2950"
   reset the config to its default options?
   

   then reset if yes / quit if no
