    ZEPPELIN-1270. Remove getting SQLContext from SparkSession.wrapped()

    ### What is this PR for?
    SparkSession.wrapped is only for spark 2.0 preview, it is not supported in 
spark 2.0 release. So I think we can remove that piece of code. Otherwise we 
will get the following error in log which might be a little confusing.
    ```
    08:05:44,946 - Thread(pool-2-thread-3) - (Utils.java:40) - 
org.apache.spark.sql.SparkSession.wrapped()
