Prevent test/demo app config from leaking into consuming app.

As of Ember CLI <I> and up, the file located at
`config/environment.js` will be used to return the addon's own
configuration.  That conflicts with the way this library is using
`config/environment.js` (for the testing/demo app).

This simply overrides the default config hook to return nothing.
