GraphQL slice test - Include all beans used to setup GraphQL source

GraphQlTypeExcludeFilter currently allows JsonComponent, RuntimeWiringConfigurer, Converter and GenericConverter beans only. But DataFetcherExceptionResolver, Instrumentation and GraphQlSourceBuilderCustomizer are used in setting up the GraphQL source. Hence these beans should also be included by default.
