Prepare does not work correctly if you have npm module and tns plugin in same project

[dtopuzov]

Steps to reproduce:
tns create TestApp
cd TestApp
tns platform add android
tns plugin add nativescript-social-share
tns prepare -> everything is fine at this point
npm install nativescript-appversion --save
tns prepare -> In platforms/android/assets/app/tns_modules/nativescript-social-share all js files are missing.

As a workaround you can delete node_modules directory before preparing the project (after npm install <...> --save. This way everything will be prepared correctly.
