[Coin-lpsolver] Shouldn't primalPivotResult update reduced costs?

Just to make it clear. I said that primalPivotResult was taking twice as
long (as before). I haven't compared the times with an explicit call to
setObjectiveAndRefresh following primalPivotResult.

John, I believe you made some mistake. Now the old code (from my first
e-mail):

  setObjectiveAndRefresh(_originalObjective); 
  pivotStatus = primalPivotResult(in, 1, out, outStatus, stepSize,NULL);
  printf("1 - %e\n", getReducedCost()[653]);
  setObjectiveAndRefresh(_originalObjective);
  printf("2 - %e\n", getReducedCost()[653]);

is printing

  1 - 0,000000e+00
  2 - -7,825281e-02

Once again.

Best,

Paulo
