[ZEPPELIN-3698] Zeppelin stops working after a few days of uptime with RemoteEndpoint unavailable, outgoing connection not open
### What is this PR for?
Notebooks suddenly show up empty (are not loading) and the logfile (apache-zeppelin-dev.log) shows the following error:
```
org.eclipse.jetty.websocket.api.WebSocketException: RemoteEndpoint unavailable, outgoing connection not open
at org.eclipse.jetty.websocket.common.WebSocketSession.getRemote(WebSocketSession.java:252)
at org.apache.zeppelin.socket.NotebookSocket.send(NotebookSocket.java:70)
...
```
It seems that checking the `WebSocketException` after `NotebookSocket.send` will solve this problem .
### What type of PR is it?
Bug Fix
### What is the Jira issue?
* issue: https://issues.apache.org/jira/browse/ZEPPELIN-3698
