BUG/MEDIUM: mux-h1: Don't set the flag CS_FL_RCV_MORE when nothing was parsed

When we start to parse a new message, if all headers have not been received,
nothing is copied in the channel's buffer. In this situation, we must not set
the flag CS_FL_RCV_MORE on the conn-stream. If we do so, the connection freezes
because there is no data to send that can reenable the reads
