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()
java.lang.NoSuchMethodException: org.apache.spark.sql.SparkSession.wrapped()
at java.lang.Class.getMethod(Class.java:1786)
at org.apache.zeppelin.spark.Utils.invokeMethod(Utils.java:38)
at org.apache.zeppelin.spark.Utils.invokeMethod(Utils.java:33)
```
