URL rewrite module - REQUEST_URI does not contain querystring

Using server variable REQUEST_URI does not seem to work when working with query strings.

This does not work:

```xml

```

As a workaround, I appended the QUERY_STRING variable to the condition. But this does not seem to be in line with the [IIS documentation](https://docs.microsoft.com/en-us/iis/extensions/url-rewrite-module/url-rewrite-module-configuration-reference#accessing-url-parts-from-a-rewrite-rule) I found

This is the workaround:

```xml

```

I'm using version 2.0.1 of the Microsoft.AspNetCore.Rewrite package
