Improve the PrimaryConvention's diff tool launch behavior so that the diff tool can be launched any time that the run contains a single failure and that single failure has no compact representation. This allows the behavior to run even when the full suite is executed, rather than forcing the developer to run the single failure a second time in order to get the behavior.
