[CARBONDATA-2217]fix drop partition for non existing partition and set
FactTimeStamp during compaction for partition table
**Problem:**
1)when drop partition is fired for a column which does not exists , it
throws null pointer exception
2)select * is not working when clean files operation is fired after second
level of compaction, it throws exception sometimes
**Solution:**
1)have a null check , if column does not exists
2)give different timestamp for fact files during compaction to avoid
deletion of files during clean files
3) This PR also contains fix for creating a pre aggregate table with same
name which has already created in other database
