SendException and SendMessage fails for content type: application/json

Exception Message: "Incorrect Content-Type: application/json; charset=UTF-8"
StackTrace

   at Microsoft.AspNetCore.Http.Features.FormFeature.ReadForm()
   at RollbarDotNet.Builder.RequestBuilder.BuildRequest(Request request)
   at RollbarDotNet.Builder.RequestBuilder.Execute(Payload payload)
   at RollbarDotNet.Rollbar.ExecuteBuilders(Payload payload)
   at RollbarDotNet.Rollbar.SetupPayload(RollbarLevel level)
   at RollbarDotNet.Rollbar.<SendException>d__14.MoveNext()

This could be because I am calling SendException from custom middleware.

Thanks.

This could be because I am calling SendException from custom middleware.

Actually entirely possible that this is the cause -- I'm wondering if something isn't available that RollbarDotNet's BuildRequest function is expecting, because it crawls all over the context trying to gather information about the current request.

Seems to be caused when trying to access context.Request.Form

Only reproduction I can find of this issue is here: aspnet/Security#1069 and here: JeffreySu/WeiXinMPSDK#283, the second link suggests we can add a second check to the post check to validate there are form fields available.

I'll see about getting this done and out later today @daithimaolain.
