Title: Fixed select error when marker icon layer not present

If a point indicator icon layer does not exist or is not present, do not
attempt to remove it from the map. This fixes some select problems when
polygon or linestring areas were selected instead of points, and
subsequent selections would not bring up an info box for the data set.
