Making suggestion

We addressed your comments from yesterday but we cannot get the right routes. When clicking on "Make a suggestion", the path is `initiatives/suggestions/new` instead of `initiatives/fixture-0/suggestions/new`.

After submitting the suggestion, the new suggestion is displayed in `initiatives/suggestions/fixture-0`instead of `initiatives/fixture-0/suggestions/101`.

One thing we found with console.log in routes/suggestions/new.js is that `model.get('id')` is `fixture-0`and there does not seem to be any attribute related to the id of the suggestion model (ie `100`).

The other thing we found out is that templates, routes and controllers directories should not follow the nested pattern of the routes.
