[ZEPPELIN-853] Fix Last update at X by Y

### What is this PR for?
This is a hotfix to solve https://issues.apache.org/jira/browse/ZEPPELIN-853. The reason seems to be that new `AuthenticationInfo` field added to paragraph structure doesn't exist in old notebooks and check for non-existence wasn't complete.

### What type of PR is it?
Hot Fix

### Todos
* [x] - fix `if statement`

### What is the Jira issue?
[#853](https://issues.apache.org/jira/browse/ZEPPELIN-853)

### How should this be tested?
Start zeppelin and go to any existing notebook, check console not to have stacktrace mentioned in the issue.

### Questions:
* Does the licenses files need update? No
* Is there breaking changes for older versions? No
* Does this needs documentation? No
