Found a fix for a bug causing the functional tests to segfault at DeterministicModelBisimulationDecomposition.Die.

- By setting the blocks to be not sorted and unique a different constructor is used by the boost container. This prevents the segfault.
|- I can't say exactly why this works nor do I know if the blocks are actually sorted and unique in the sense meant by the underlying container implementation.
