Setting SocketIOClient's config value after initialization results in unusable client

[thully]

In my code, I tried to initially set up a SocketIOClient object and then set the config value later. While the API allows this to be done, the client will not connect. I was able to work around this by just creating a SocketIOClient object. However, if modifying the SocketIOConfiguration after initialization isn't supported, config really should be a get-only field.
