Unmet peerDependencies break adding of platform

[vchimev]

If there are not satisfied peerDependencies then adding a platform fails. This leaves the project in a broken state with the platform added as a dependency.

Steps:

git clone git@github.com:NativeScript/nativescript-sdk-examples-ng.git
cd nativescript-sdk-examples-ng
git reset 642bde0cbea6f70659972d6bbf1a2bb6f2f502a4
npm install
tns run ios --log trace

Details:

• node v6.10.2
• npm 4.2.0

Output:
