Delete suggestion



`initiative.suggestions`is an array of classes: [Class, Class, Class], and the id is a property of each class, e.g. `initiative.suggestions[0].id`. I can't figure out how to find the matching id without either looping through the class array or storing the ids into an array then using `find`to find the one that matches `suggestion_id`

About deleteRecord, if you don't do it, `initiative.get('suggestions').content.content.length`= 3 (all 3 suggestions), and after removeObject, `initiative.get('suggestions').content.content.length´= 2. So it seems that the suggestion has to be explicitly removed from the initiative, and not just from suggestions.
