Luigi Pinca 9b7a6914a7 net: emit 'close' after 'end'
Currently the writable side of the socket is closed as soon as `UV_EOF`
is read regardless of the state of the socket. This allows the handle
to be closed before `'end'` is emitted and thus `'close'` can be
emitted before `'end'` if the socket is paused.

This commit prevents the handle from being closed until `'end'` is
emitted ensuring the correct order of events.
