The hypergeometric tests are on the support of the distribution and
should never fail. And the outcome is not random.

 The test of logser with N = 100000 also should be pretty exact and
fail only with very low probability in the patched version. But again
this is testet in scipy.stats.

I think Sturlas idea to find a random seed that differentiates before
and after will be better for numpy, and using only a small sample size
e.g. N=1000, since it's pretty fast. But since I don't have an
unpatched numpy version available right now, I cannot do this.
