v1.3.x: Let the rerun formatter handle outlines with the expand option

I think that #503 and #504 were intended to be targeted to the v1.3.x-bugfix branch, rather than the master/v2.0 branch. The scenario in #504 is passing in v2.0, if it is just updated to use the v2.0 step definitions, see #709.

This PR adds the corresponding scenario to the rerun formatter feature also in v1.3.x, and updates the rerun formatter so this scenario passes.
