Minimal example

import numpy as np
import cocoex as ex

suite = ex.Suite("bbob-biobj", "", "dimensions: 5,40 function_indices: 9-20")

observer = ex.Observer("bbob-biobj-old", "number_target_triggers: 5")

problem = suite[0]
problem.observe_with(observer)

problem._best_parameter("print")
x_opt = np.loadtxt("._bbob_problem_best_parameter.txt")

Fix crash in bbob_biobj_problem_best_parameter_print
f7e106e 
Previously bbob_biobj_problem_best_parameter_print assumed that the
problem was not logged and could misinterpret the ->data member
otherwise which lead to bad data or crashes.

Partially fixes #2224.
