Instead of saving task state in a class variable that is later introspected by further test code just remove that concept (which doesn't work in multiprocessing or worker engines which can not have access those types of shared/globally available concepts due to how they run) and use a specialized listener that can gather the same information in a more decoupled manner (and it will work in multiprocessing and worker engines correctly). This allows our engine test cases to work in those engine types which increases those engines test coverage (and future coverage and engine tests that are added). Fixes a bunch of occurrences of bug 1357117 as well that were removed during this cleanup and adjustment process... Change-Id: Ic9901de2902ac28ec255bef146be5846d18f9bfb
