PlotCommitList: Remove handling of children that have no lane yet
Child commits always have a lane assigned when their parents are processed, so this code is no longer necessary. Children only assign themselves to parents in PlotCommitList.setupChildren(), which is called from enter(), when the child is processed. If the child leaves enter() it should always have a lane assigned. As a result of this, when processing a parent, all its known children already have lanes assigned. If the underlying RevWalk emits a parent before one of its children (which it should not do), the parent does not know of the child emitted later, because setupChildren() has not been called for the child yet. So even in this case, no child without a lane is encountered when processing a (parent) commit.
