half hearted fix: order of hashmap entries is implementation dependent

a real fix would be to rewrite the test to collect the retrieved
values and do a structural verification of the results. This
would mean to write a lot of code for such a marginal topic,
which was implemented just for sake of completenes anyway.

Hopefully my lack of "motivation" doesn't backfire eventually ;-)
