make sure invalid geometries are always deleted from place

Browse Source 
This solves a bug with updating large invalid geometries. These
geometries have an entry in place but not in placex. Thus, place_insert
tries to delete the place entry and reinsert it on update. Deletion would
fail because self-intersecting polygons still have an area and large
areas are not deleted.
