"Create new torrent from folder..." duplicates every file in child folders, and moves them to the root on-disk

[R0quef0rt]

What version of WebTorrent Desktop are you using?
0.24.0

What operating system and version?
Windows 10 Pro 1909

What happened?
I added a new torrent by using the "Create new torrent from folder..." option. I imported a folder (MyFolder) with the following structure:

MyFolder
MyFolder\file1.mp3
MyFolder\MyChildFolder\file2.mp3

After doing so, my directory structure on-disk looks like this:

MyFolder
MyFolder\file1.mp3
MyFolder\file2.mp3
MyFolder\MyChildFolder\file2.mp3

What did you expect to happen?
I don't expect my torrent client to create duplicates of my files on-disk. I would expect it to preserve directory structure. I would not expect it to modify my files at all.

Are you willing to submit a pull request to fix this bug?
Yes, but I am unlikely to be able to help.
