Fixed JOIN sequence
Fixed JOIN sequence

When JOINing a channel, the servers should reply with JOIN,
RPL_TOPIC and RPL_NAMREPLY  to show the client that the join was
successful, tell the client what the current topic and who is
currently in the channel.

If RPL_NAMREPLY is omitted, the user list may stay empty in
some clients
