with the change to cordova-fetch for local paths, cordova plugin add SOMELOCALPATH --link doesn't work anymore.
The plugin first gets `npm installed` into your cordova project (so it now lives in node_modules), and then it gets copied into your plugins directory. During the copy to your plugins directory step, that is when the symlink gets created. So the symlink points to your node_modules/PLUGINDIR and not the local path to your plugin.
I believe the solution to fixing this would be to `npm link` the plugin instead of `npm install` when adding it with `--link` flag.
