[CARBONDATA-2426] Added fix for data mismatch after compaction on Partition
with Pre-Aggregate tables
**Problem:** Partition directory is getting deleted when one on the
segment is marked for delete and another segment is loaded in the same
partition.
In case of aggregate table we only have partition specs for the specified
segments therefore when the deleted segment is scanned against locationMap for
stale partitions one of the valid partition is considered as stale as we dont
get partitionSpecs for all the segments.
**Solution:** Delete the index file instead of the partition directory and
then delete the directory if it is empty.
