proj_create_crs_to_crs(): fix when there are only transformations with ballpark steps
Currently we would discard all operations, resulting in a PJ object with
zero candidates. Better use those operations if nothing better is available.
Was seen on transforming from ETRS89 / UTM zone 31N + EGM96 height to WGS 84 (G1762).
The horizontal transformation from ETRS89 to WGS 84 (G1762) is a ballpark one.
