ConfigSpace `get_neighbours` of log transformed `UniformIntegerHyperparameter` can hang

from ConfigSpace import UniformIntegerHyperparameter

u = UniformIntegerHyperparameter("u", 1, 10, log=True)

rs = np.random.RandomState(3)
u.get_neighbors(3, rs)
# Hangs....

This is possibly related to #187.

The refactor for #187 added a check which makes the given input invalid and the output is now
