Fix #925 Memory Leak while WebSocketServerHandshakeException or Channel failed

[HashJang]

fix #925

[HashJang]

this logic should be implemented in com.corundumstudio.socketio.handler.ClientHead#onChannelDisconnect() method without ScheduledExecutorService usage.

but like the bug this time, onChannelDisconnect is called indeed(due to scheduled ping timeout), but the namespaceClients does not contain the client which throw WebSocketException, which result in the uuid2clients does not remove it.

however, i cannot complain if you stick that this is not required, i can still remove it and keep the memory leak fixed, first thing first @mrniko

I think it's fixed in https://github.com/h3mant-1/netty-socketio/commit/fb467074a62c2528fdb1ba0f5a0610e90ddf3928
