This way, find_root works reliably. This seems to behave well in terms of other projects not breaking. We investigated ditching the rename of the folder to node_modules, but not doing so still confuses browserify.
The browserify-versionify transform assumes the cwd will be the module’s folder. It uses `find-root` to traverse upwards and find a package.json. Right now the cwd is set to “/tmp/webtorrent115012-16911-2wbt66” when browserifying. This PR changes it to “/tmp/webtorrent115012-16911-2wbt66/node_modules/webtorrent”, for example.
