[SPARK-10663] Removed unnecessary invocation of DataFrame.toDF method. The Scala example under the "Example: Pipeline" heading in this document initializes the "test" variable to a DataFrame. Because test is already a DF, there is not need to call test.toDF as the example does in a subsequent line: model.transform(test.toDF). So, I removed the extraneous toDF invocation.
