Names of all applications in mobile-contacts start with "contacts-mobile-":
server/contacts-mobile-picketlink-secured
server/contacts-mobile-proxy
client/contacts-mobile-android-client
client/contacts-mobile-ios-client
client/contacts-mobile-cordova
client/contacts-mobile-webapp

In helloworld quickstart, this is not the case:
android
cordova
ios

I think the naming should be consistent between the quickstarts
