title: Service stack server OnReconnect event is not fired when server reconnected successfully
body: <p>I am working on the serviceStack and react-redux project.
  I have to create functionality to detect that the user is connected to the network or not.
  For that, I'm using SSE reconnect event to get the response,
  what I did is:
  I checked the response from the onReconnect event if it gives error then I consider I user is offline.
  Which is working fine.
  But once a user connected to the OnReconncted event doesn't fire.</p>
  
  <p>Ps: I don't want to use onConnect event as it fires on page refresh also.</p>
  
  <p>Thanks in advance for the help.</p>
