Feature Request: Add a type's dataId automatically

[baconcheese113]

As mentioned in #123 it could help users avoid cache bugs and copy/pasting id throughout all their queries if it was added automatically to fields that don't specify it, just like how __typename is. No error is reported when a user doesn't add id yet their cache will fail to update, which can be unexpected behavior

It's a habit to add it to all fields for people that have been working with graphql for a while, but it's not immediately obvious to new graphql users. It would shrink queries and make it more apparent what fields the widget is actually using

I just hit a couple of these exceptions like CacheMissException. Took a while to figure out that a specific query was missing the id field.

Highly agree that this would be super nice to have!
