ProxyClient adds ProxyResult with http status code 500 during redirect

[alrod]

proxy_test.zip

After executing:

azure-functions-host/src/WebJobs.Script/Description/Proxies/ProxyClientExecutor.cs

Line 29 in f9540d6

await _proxyClient.CallAsync(new object[] { request }, proxyFunctionExecutor as IFuncExecutor, logger);

request.HttpContext["MS_AzureFunctionsHttpResponse"] is replaced with ProxyResult 500 error.

The issue started to appear after moving function runtime from ASP NET Core 2.1 to 2.2.
Most likely we need to update Microsoft.Azure.AppService.Proxy.Client to ASP.NET Core 2.2. and see if some ResultRedirect test is broken(if there is one)
