manager: fix the experiment generator

- All simulations were not performed due to an error on allocation of
  simulations to different ranks (Closes #145).
- The max index of the experiment generator is now excluded from the
  simulations to perform for a given rank (the behavior is now the same
  between mvle and the manager). Tests are updated.
