Taking a pane out of a control client's stream without crashing the server, and so [`crate::control::ControlSender::mute_pane`] using `off`.

Before this release `refresh-client -A <pane>:off` leaves the output
blocks already queued for that pane in place, while the pane stops
holding the server's read buffer back. Writing those blocks later
reads past the end of a buffer the server has drained, and the server
segfaults. `mute_pane` pauses the pane below this release instead,
which discards the queue on every supported release.
