[SPARK-5926] [SQL] make DataFrame.explain leverage queryExecution.logical
DataFrame.explain return wrong result when the query is DDL command.
For example, the following two queries should print out the same execution
plan, but it not.
sql("create table tb as select * from src where key > 490").explain(true)
sql("explain extended create table tb as select * from src where key > 490")
This is because DataFrame.explain leverage logicalPlan which had been forced
executed, we should use the unexecuted plan queryExecution.logical.
