Hi,

We were stuck on a failing unit test for two days on H2GIS. Then we 
understood that we were changing a geometry in-place. In conjunction with 
the object cache, a WKB hash of a ValueGeometry does not fit with the 
mutated Geometry instance.

This fix simply return a Geometry clone when the user do rs.getObject( )
