cancel ConnectAsync when calling Disconnect

Hi Team,

Thanks for doing an amazing job to maintain this library.

I have a question that is how can we stop ConnectAsync() while it's running?
In version 3.0.6 we can use Dispose() to trigger the cancellation token and cancel the ConnectAsync() before the timeout
but in the recent version 3.0.7, I notice that the Dispose() method no longer triggers the cancellation token which will let the ConnectAsync() retry forever.

Test case:

• Call ConnectAsync while there is no network
• It will keep retrying to connect
• when want to close the app/ reset the socket io client ...etc -> no way to cancel the retrying
• Call dispose(). the socket io still retrying to connect.

I would suggest adding back _cts.Cancel() to the Dispose method or on DisconnectAsync() to make sure we don't retry blindly.
