Disposing UnityWebRequest gets thrown error

[hagabooga]

I get this thrown error and I know it's because I dispose the UnityWebRequest manually. Should there be a check around (at ./Library/PackageCache/com.cysharp.unitask@73d86259ce/Runtime/UnityAsyncExtensions.cs:903) or should I deal with this outside of the UniTask library?

It seems that if I dispose of the request, AsyncOperation.webRequest will be null.

        var req = UnityWebRequest.Get("https://google.com");
        var operation = req.SendWebRequest();
        req.Dispose();
        await operation;

Hello, Perhaps you are disposing of the UnityWebRequest in the process..?
If so, it seems like an illigal operation. Please confirm.

I fixed it in #494, so that you get the proper error message instead of a null error.

I checked it and I get a proper error message instead of a null error now. Thanks!
