Let the rerun formatter includes all scenarios when the background fails

As noted in #650 and #653 the rerun formatter only includes the first scenario when (a step in) the background fails. The root cause of this is that Cucumber v1.3.x skips the rest of the scenarios of the feature in this case.

Let the rerun formatter includes all scenarios in the feature if the background fails. It is realized by changing the rerun formatter to also include skipped scenarios.
