[CARBONDATA-1947]fix select * issue after compaction, delete and clean
files operation
**Problem**: fix select * issue after compaction, delete and clean files
operation
**Analysis**: during compaction the timestamp of fact file and the load
starttime present in metadata details are different for the same segments, so
when the delete operation is executed and after that clean files is called,
since there is a timestamp difference, it will delete the carbondata file which
inturn gives empty result for select query.
