Attempting to connect to a nonexistent server doesn't throw a ButtplugError

[EskCresh]

I attempted to initiate a connection while Intiface was closed to trigger a connection error, as in:

connector = new buttplug.ButtplugBrowserWebsocketClientConnector('ws://127.0.0.1:12345');
client = new buttplug.ButtplugClient('test');
try {
    await client.connect(connector);
} catch(e) {
    console.log(e);
    console.log(e.name);
    console.log(e.message);
}

My intent was to be able to use the error details for more robust logging. I figured it would be of type ButtplugClientConnectorException, but at least of ButtplugErrror, or even Error. Instead, I got an Event with type: "error" and target of the WebSocket object. I'm not sure what other WebSocket issues might return Events.
