Installation of scoped plugin also installs conflicting unscoped plugin with same name

if there is unscoped package with same name as scoped package, both will be installed.
As result you will end up with two (potentially conflicting) packages.

How to reproduce:
1. create new cordova project:
cordova create myApp org.apache.cordova.myApp myApp
2. add plaftofm
cordova platform add android
3. install scoped package:
cordova plugin add @mauron85/cordova-plugin-background-geolocation@3.0.0-alpha.4
Expected Behavior
Only single package @mauron85/cordova-plugin-background-geolocation will be installed

Actual Behaviour
Two packages will get installed:
1. @mauron85/cordova-plugin-background-geolocation - https://www.npmjs.com/package/@mauron85/cordova-plugin-background-geolocation
2. cordova-plugin-background-geolocation - https://www.npmjs.com/package/cordova-plugin-background-geolocation
They are completely different and incompatible. As result cordova project won't compile.

Console output:
Installing "cordova-plugin-background-geolocation" for android
Installing "cordova-plugin-geolocation" for android
Installing "cordova-plugin-dialogs" for android
Adding @mauron85/cordova-plugin-background-geolocation to package.json
Saved plugin info for "@mauron85/cordova-plugin-background-geolocation" to config.xml
