fix: ensure query object is traversed

[erikkessler1]

Problem

The way we override the Schema#query method makes it so that we don't call add_type_and_traverse when setting the new query type like graphql-ruby does here. Currently we only add and traverse the query type when accessing the query.

The following script demonstrates this:

require 'bundler/inline'

gemfile do
  source 'https://rubygems.org'
  gem 'apollo-federation'
end

class CatType < GraphQL::Schema::Object
end

class QueryType < GraphQL::Schema::Object
  field :cat, CatType, null: false
end

class Schema < GraphQL::Schema
  include ApolloFederation::Schema

  query QueryType
end

p Schema.get_type('Cat')
#=> nil

Solution

This PR makes it so that we call super(federation_query_object) when the new query object is being set.
