BUG: Correct stop condition description

When OnePlusOneEvolutionaryOptimizerv4::StopOptimization was manually
called the stop description incorrectly indicated that the maximum
number of iterations had been reached. Only over write stop condition
descriptions, when the maximum number of iterations have been
exceeded.
