Cleanup code by removing patchFailedToBuild and patchFailedTests properties. Those were added in very early days of this instance bringup, when corresponding steps (e.g.: UnApplyPatchIfRequired) were listed statically in factories.py. Later on we started invoking steps dynamically using addStepsAfterCurrentStep and UnApplyPatchIfRequired is no longer called in factories.py. We can just remove all this patchFailedToBuild and patchFailedTests properties logic.
