Allow electrode-archetype-react-app-dev to be installed with yarn

[bodawei]

At times, I need to install some of the electrode modules with something like npm. I'd like to be using yarn, but right now that reports an error because of a problem with electrode-electrify-rect-component.

> rm -rf node_modules  # you wouldn't ordinarily do this. I'm just doing it to demonstrate a quick way to this problem
> yarn install
yarn install v0.19.1

Note

• There is an issue already filed on electrode-electrify-react-component electrode-electrify-react-component is not compatible with 6.x of nodejs with yarn electrode-electrify#26
• As soon as the pull request for this ( electrode-electrify-react-component is not compatible with 6.x of nodejs with yarn #26 electrode-electrify#27 ) is accepted, and the update is pushed to npm, I can provide a pull request for the relevant electrode modules.

This issue seems to be wrong. When I upgraded everything to the latest, yarn no longer tries to install electrode-electrify-react-component, so the problem isn't encountered. I didn't investigate to see what, specifically, changed.
