[CARBONDATA-1076] Join Issue caused by dictionary and shuffle exchange
When under join aggregate plan is there then there is a high chance of
having same partitioning so it will generate single exchange instead of two. So
in that case better push down the decoder to aggregate rather than handling at
join phase.
