Remove double adding of MHD_HTTP_HEADER_CONNECTION response header

MHD_create_response_for_upgrade() already adds the MHD_HTTP_HEADER_CONNECTION response header, so
the additional MHD_add_response_header is wrong.

In our application it caused, that on a Apple iPad, the websocket was immediately closed by the
browser(Safari, Chrome, Opera) after the protocol upgrade. Browsers on Linux, Android did not had this issue.
