[SPARK-20359][SQL] catch NPE in EliminateOuterJoin optimization catch NPE in EliminateOuterJoin and add test in DataFrameSuite to confirm NPE is no longer thrown ## What changes were proposed in this pull request? catch possible NPE in this line ```val v = boundE.eval(emptyRow)``` and conclude the optimization can not be performed. ## How was this patch tested? Added test in DataFrameSuite that failed before this fix and now succeeds. Note that a test in catalyst project would be better but i am unsure how to do this. Will look into it now.
