Android resources not copied correctly when specified in config.xml

Android resources are not copied correctly when specified in config.xml

Info:
I have created a basic app to illustrate the issue, if you clone the following URL and follow the instructions below, you will see: https://github.com/kelvindart/CordovaAndroidResources

Issue:
Running `cordova prepare` or `cordova build` does not seem to move the specified resources correctly, and removes them to the root of the project, not within the android project.

Expecting:
`resources` to be merged in `platforms/android/res/` after running one of the above two commands.

Steps to reproduce:

1. Clone the following Git repo: https://github.com/kelvindart/CordovaAndroidResources
2. Run `cordova prepare`.
3. Observe a newly created folder in `./` named `res` - inside here are android folders for the various screen sizes, containing your resources specified in `config.xml`
4. Further note, in `./platforms/android/res/` the old resources are still present.

(N.b. I am unable to add the relevant cordova-android@6.0.0 tags.)
