model_aligner has different result with version <=3.6

[oUp2Uo]

Describe the bug
Using model_aligner to change the scale of the result.
As the document written, custom should have the same result as old version, but it is not.
Using custom could not rescale correctly. The coordinate does not change.

To Reproduce
Steps to reproduce the behavior:

1. Version 3.6, run

COLMAP.bat model_aligner --input_path C:\Users\Up2U\Desktop\test\5\undistorted\sparse --output_path C:\Users\Up2U\Desktop\test\5\undistorted\sparse\geo-registered-model --ref_images_path C:\Users\Up2U\Desktop\test\5\geo_registration.txt --robust_alignment_max_error 3

2. Version 3.9.1, run

COLMAP.bat model_aligner --input_path C:\Users\Up2U\Desktop\test\5\undistorted\sparse --output_path C:\Users\Up2U\Desktop\test\5\undistorted\sparse\geo-registered-model --ref_images_path C:\Users\Up2U\Desktop\test\5\geo_registration.txt --ref_is_gps 0 --alignment_max_error 3

Expected behavior
They should have a similar result,
but version 3.9.1 using custom could not rescale correctly. The coordinate does not change.
Also the printed calculation result is different.
