--ignore-engines is... ignored

This is a bug!

What is the current behavior?

The --ignore-engines flag does not work. Our project (debugger.html) won't install because of a dependency enforcing node 4, and I'm on node 6. It still doesn't work with --ignore-engines.

% yarn --ignore-engines
yarn install v0.15.1
