FileTransferManager sends wrong error code on stream rejection

Should be code 403 but it sends 406 resulting in weird error messages / exceptions when rejecting the file transfer before the stream was negotiated.

Thanks for reporting

I wonder if it’s true of InBandBytestreamManager and Socks5BytestreamManager too.
