remove_spikes does not remove spike

[vschoech]

My "tc::geo::polygon" type is actually a multi-polygon, using a polygon type that is based on int, oriented counter-clockwise and open (not closed). I am using boost 1.70.0. Please consider the following example:

tc::geo::polygon<int> polygon_;
boost::geometry::read_wkt("MULTIPOLYGON(((4287 2160,5984 2160,4287 2160)))", polygon_);
boost::geometry::remove_spikes(polygon_);
boost::geometry::is_empty(polygon_); // **** returns false! ****

As far as I can tell from our discussions, the correct result would be the empty multi-polygon. Here is the summary of my understanding of this issue: http://lists.boost.org/geometry/2014/11/3237.php
