* Changes the event to send when a channel is shared or unshared
Before we were sending the CHANNEL_CONVERTED websockets event, which
is intended to notify of a public channel being converted into a
private one, so the interface was showing the channel as private until
the client was refreshed.
Now a full channel update event is sent when the channel is shared or
unshared, so the interface gets the new information correctly.
* Fix message type on command tests
