BUG/MINOR: mux-h1: Wake busy mux for I/O when message is fully sent

If a mux is in busy mode when the outgoing EOM is consummed, it is important to
wake it up for I/O. Because in busy mode, the mux is not subscribed for
receive. Otherwise, it depends on the applicative layer to shutdown the H1
stream. Wake it up allows the mux to catch the read0 as soon as possible.

This patch must be backported to 1.9.
