bug 1889 - don't quit moxi on empty JSON re-config messages

We might get these empty JSON re-config messages from the mock ruby
sinatra server, since it's actually not a proper streaming server...

http://localhost:4567/pools/default/bucketsStreamingConfig/default

This change doesn't actually fix the issues of working with
bucketsStreamingConfig, but at least moxi won't exit() anymore.
