ENG-2549 plannertester baselines purposely improved

Here's the slightly improved plan, (using a different index with a greater number of indexed columns, 2/3 vs. 1/2).

select * from l where lname=? and b=0 order by id asc limit ?;

Explained plan:
RETURN RESULTS TO STORED PROCEDURE
 LIMIT with parameter
  ORDER BY (SORT)
   RECEIVE FROM ALL PARTITIONS
    SEND PARTITION RESULTS TO COORDINATOR
     INDEX SCAN of "L" using "SYS_IDX_PK_LOG_10021" (range-scan 1/2 cols)
     inline (LIMIT with parameter)
