    chatView: Update join time on channel changes
    
    The code introduced in commit d2bbe17a76578e to prevent status
    messages flooding the chat log when connecting broke when we
    decoupled rooms and channels - rather than setting the join time
    once on room creation, we need to update it every time we get
    a connection established (i.e. a channel).
