The code took care to not delete planner-points when no
points are selected. However, it assumed that all selected
objects are planner-points. But then it checked whether
the selected object actually is a planner-point. So which
is it?
Remove the outter check for an empty selection. This makes
things more logical and more robust, should there ever
be other objects that can be selected.
