cart: Avoid discontinuity at poles in the inverse case

2020-02-08T09:50:31+00:00

This should avoid issues with numerical stability as uncovered in
https://github.com/OSGeo/PROJ/issues/1906.

Practically speaking this change isn't going to affect real life
scenarios since the position of the center of the Earth is rarely
expressed in geodetic coordinates.
