Restoring multiple platforms fails

Steps to reproduce:
1. Create a blank app: cordova create test com.app.test test
2. Add and save a platform: cordova platform add --save ios
3. Add and save another platform: cordova platform add --save android
4. Remove the platforms: cordova platform remove android ios
5. Try to restore platforms automatically: cordova prepare

Expected: both platforms installed and prepared
Actual:

Error: Trying to initialize npm when settings have not been restored from a previous initialization.

Running cordova prepare again fixes the issue.
