@homebound/graphql-id-linter

According to apollo-client's issue 2510, the apollo client really, really wants you to include ids in every query that touches a type, so that it can maintain its cache.
In theory this is getting fixed in apollo-client 3.0-beta, but always returning id is probably not a bad idea anyway.
Credits, this is a ~80% copy/paste of Cecchi's solution on this comment.
