Description

This pull request moves the screenshot fallback path handling into the main process, that allows us to remove a use of a Node.js API in the renderer process. After this pull request the only remaining Node.js API uses in the renderer process is the video/audio/subtitle download logic.

Testing

1. In the dev data location (Electron folder instead of the FreeTube one), check that screenshotFolderPath doesn't exist in the settings.db file, if it does remove that line.
2. Start FreeTube
3. Open the player settings
4. Make sure taking screenshots is enable and ask for path is disabled.
5. Check that it shows the correct path (should be the pictures folder in your user profile + Freetube).
