ENH: Increase coverage for itk::OnePlusOneEvolutionaryOptimizer

Increase coverage for `itk::OnePlusOneEvolutionaryOptimizer`:
- Exercise basic object methods using the
  `ITK_EXERCISE_BASIC_OBJECT_METHODS` macro.
- Test the Set/Get methods using the `ITK_TEST_SET_GET_VALUE` macro.
- Test the boolean ivars using the `ITK_TEST_SET_GET_BOOLEAN` macro.
