    [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.
