API responses returned from create requests do not return custom fields

[atruskie]

For a resource just created with POST /resource we return the created record but none of the AREL based virtual custom_fields2 definitions are included.

That's because we use a simple (and undecorated by our magic/helpers0 model.save call to persist and load the new object to the database.

We need to find a better way to either:

• apply a projection to the .save call so additional virtual attributes will be returned with the model on creation and emitted in the api
• or a reload of our model after creation using Filter::Single.new so that all the extra properties are returned.
