BUG/MEDIUM: mux-h1: Report EOI when a TCP connection is upgraded to H2

When TCP connection is first upgrade to H1 then to H2, the stream-connector,
created by the PT mux, must be destroyed because the H2 mux cannot inherit
from it. When it is performed, the SE_FL_EOS flag is set but SE_FL_EOI must
also be set. It is now required to never set SE_FL_EOS without SE_FL_EOI or
SE_FL_ERROR.

It is a 2.8-specific issue. No backport needed.
