Possible ambiguous GraphQL request logging

[ubiuser]

Based on the gqlgen lifecycle example presented in https://github.com/99designs/gqlgen/blob/ddd825ef62f1fa7cbc0824c1696f72a3c67d78e0/graphql/handler.go#L45, multiple responses can be sent for the same subscription operation, which means

graphql/server/server.go

Line 115 in 76180de

gh.AroundResponses(GqlLoggingMiddleware)

should probably use AroundOperations instead of AroundResponses to avoid multiple log lines for the same request.
