Deleting a JsonModel from a CollectionOfJsonModels doesn't emit deleting or deleted events.

[jwadhams]

JsonModel implements a ->delete() method that emits deleting and deleted Eloquent events, then sets the model to null in the upstream model.

The problem is this won't work of the JsonModel is in a CollectionOfJsonModels, because the collection expects every element to continue to validate as the original model.

$deal->vehicles->find($vin)->delete(); // throws JsonSchemaValidationException : Vehicle contains invalid data!

so instead we've taken to using the very un-Eloquenty approach

$deal->vehicles->forget($vin)->save(); // Works but doesn't emit deleting or deleted events

Proposed Fix:

• Update ->delete to work for models in a collection.
  • This might mean giving models some way to detect "am part of a collection"
• Update collection to use ->delete (to get events) under the covers
