PreparedLineStringIntersects: Fix incorrect result for mixed-dim GC with points

@dr-jts JTS appears to be affected by the same issue.

PreparedGeometry has some level of longstanding support: https://github.com/locationtech/jts/blob/master/modules/tests/src/test/resources/testxml/general/TestPreparedPredicatesWithGeometryCollection.xml

PreparedGeometry has some level of longstanding support:

Right, I see that now. I guess it got introduced at some point since it's easier to do with the Prepared Geometry algorithms. So should be fixed.

So should be fixed.

Are you OK with this fix?

[dr-jts]

As far as I remember (and substantiated by absence of any documentation around support for Prepared Geometry with GeometryCollections), this was more of a "support by happenstance" than a planned extension. So there may well be other issues in the code.

[dr-jts]

Should add unit tests for the new Geometry.hasDimension method.
