net.server_select: Ensure onconnect is always called before onincoming This changes the code to call onconnect when the first data is sucessfully read or written, instead of simply when the socket first becomes writable. A writable socket can mean a connection error, and if the client already sent some data it may get passed to onincoming before processing writable sockets. This fixes the issue.
