allow PathPtr to be a null pointer in the PlannerSolution constructor
Fixed obscure RRT* bug.
Bug only apparent when cost function can return negative costs, sometimes resulting in an invalid rewire operation that breaks the tree structure.
There was already a check in place for this, but it was insufficient. It only performed the check on the parent node. This fix performs the check on all ancestor nodes.
