Inside Scheduler._reverse_uninstall_edges(), iover all nodes rather than just

the merge list, because some uninstall nodes may not be in the merge list
since they will be performed as part of an upgrade within a slot. This solves
a problem with Scheduler._choose_pkg() not parallelizing in some cases when
it should, due to an uninstall node not having it's edge reversed like it's
supposed to.
