SubscriptionExceptionResolver.resolveException should accept DataFetchingEnvironment

[yassenb]

Currently the method in DataFetcherExceptionResolver is Mono<List<GraphQLError>> resolveException(Throwable exception, DataFetchingEnvironment environment) while the method in SubscriptionExceptionResolver is Mono<List<GraphQLError>> resolveException(Throwable exception). It would be nice to have DataFetchingEnvironment passed in as well to include more information in our error logs.

As a side note in DataFetcherExceptionResolver.resolveException I've noticed that for some reason SecurityContextHolder.getContext().getAuthentication() returns an instance of AnonymousAuthentication when I know the user is authenticated (and the same piece of code works correctly elsewhere) and as a work-around I'm force to use environment.getGraphQlContext().get<SecurityContextImpl>(SecurityContext::class.name).getAuthentication() to get the proper authentication instance. Same applies in SubscriptionExceptionResolver
