Change GetJsonBodyAsync of HttpBasedAzureFunction to use JToken

[renebik]

Starting to use this template, but facing errors when trying to send request containing JSON array as the GetJsonBodyAsync method expects JSON object imho.
I want to use it like:
var orders = await GetJsonBodyAsync<List<Order>>(request);

Change this:

        protected async Task<TMessage> GetJsonBodyAsync<TMessage>(HttpRequest request)
        {
            using (var streamReader = new StreamReader(request.Body))
            using (var jsonReader = new JsonTextReader(streamReader))
            {
                JObject parsedOrder = await JObject.LoadAsync(jsonReader);
                var model = jToken.ToObject<TMessage>(JsonSerializer);
                Validator.ValidateObject(model, new ValidationContext(model), validateAllProperties: true);

                return model;
            }
        }

to this:

        protected async Task<TMessage> GetJsonBodyAsync<TMessage>(HttpRequest request)
        {
            using (var streamReader = new StreamReader(request.Body))
            using (var jsonReader = new JsonTextReader(streamReader))
            {
                JToken jToken = await JToken.LoadAsync(jsonReader);
                var model = jToken.ToObject<TMessage>(JsonSerializer);
                Validator.ValidateObject(model, new ValidationContext(model), validateAllProperties: true);

                return model;
            }
        }
