Avoid needless geometry processing

Mangling every geometry in the intersection machinery when importing
as waterway admin leads to slightly different geometries compared
to the same geometries imported by a sys_admin. This would create
artificial history of entries when importing alternately as
waterway admin and sys admin, once history of fairway dimensions is preserved.
