[TRAFODION-807] Fix for zero UEC counts
When CQD USTAT_ESTIMATE_HBASE_ROW_COUNT was set to 'ON' and when sampling
was not used and when logging was not used, we would sometimes get 0 UEC
counts. This was due to defective tests in the code to determine if sampling
was used. Fixed these tests. Also added code to correct the actual row count
when the estimate we get from HBase is wrong.
