Re-send network request properly when the socket is in Closing state.

This fixes the "QAbstractSocket::connectToHost() called when already
connecting/connected to <hostname>". The issue was that we were trying
to call connect on a socket that was in a Closing state. We have to
wait for the disconnected signal before we try to connect again.
