QGIS generates 2 distinct tables for 2D and 3D

[jpdupuy]

Whenever the data model includes 2 geometry columns (ie for 2D and for 3D) for a specific table : ALTER TABLE tdh_od.structure ADD COLUMN geometry_geometry geometry('CURVEPOLYGON', :SRID); ALTER TABLE tdh_od.structure ADD COLUMN geometry3d_geometry geometry('CURVEPOLYGONZ', :SRID); the QGIS Data manager will propose 2 tables with the same name to import in the canvas

Therefor, only one geometry column should be specified in the datamodel to avoid confusion (to be discussed)

Changed to only one geometry3d - see https://github.com/teksi/district_heating/pull/1/commits/ecaab5c1d59448a01b669991e1a6572966c38547
