Making suggestion

WIP
1) Suggestion is created but with the wrong id, has incrementing parent id (fixture-0, fixture-1, etc) instead of its own (100, 101, etc).
2) Error is thrown in the console:
`Uncaught Error: Assertion Failed: You can only add a 'initiative' record to this relationship`
3) template does not display saved suggestion (probably because of 2)).
starting to think we should standardize model text bodies as `body`, and not `description` or `details`. more predictable and less error prone
