Fix for NullPointerException when using code completion in the Livy
Interpreter when Shared Interpreter is enabled.
### What type of PR is it?
Bug Fix

[ZEPPELIN-3656](https://issues.apache.org/jira/browse/ZEPPELIN-3656)

Run Livy Interpreter in an environment where Shared Interpreter is enabled
and attempt to trigger code completions.
