ComputerVerificationStrategy gives false errors

I've added a new complex test that fails in OLAP. Unfortunately the test runner only marks the test as "ignored" as that's what we usually we want when a VerificationException is thrown. However, in this case the exception ("It is not possible to access more than a path element's id on GraphComputer: ...") is wrong.

Another issue that I just noticed is, that the same test throw serialization exceptions in the *Translator* test suites.
