Don't drop non-Query/Mutation resolvers passed into makeAugmentedExecutableSchema

[johnymontana]

When passing a resolvers object to makeAugmentedSchema it seems that only the Query and Mutation resolvers are included when building the schema and other type resolvers are excluded.

These other type resolvers should be included in the schema.
