Title: When fetching one record that is already in the collection, update its attributes; otherwise, create a new record in the collection

Referencing [facto's comments](https://github.com/maccman/spine/commit/1f954333b34b937f70c5baa28f4718735c5e03a6) about firing "refresh" on the collection when fetching one record via Ajax, this updates or creates collection instances as appropriate.
