Describe the bug
Using a reference cameras.sfm in SfMTransfer, and comparing the camera positions in the Meshroom GUI, between the SFMTransfer and the StructureFromMotion nodes, clearly shows the SFM step is not outputting the same positions (and different scale) as the referenced file.

This is the pipeline, the same I use in Meshroom-2023.1.0 which works as expected.

To Reproduce
Starting from standard Photogrammetry pipeline, add SfMTransfer node in between CameraInit and FeatureExtraction. Specify the reference cameras.sfm file location in the SfMTransfer Input. Compute until StrcutureFromMotion and compare the position of the cameras.

Expected behavior
The cameras from both nodes should be in the same position.

Additional context
This is all working in Meshroom-2023.1.0 (I did not test with 2023.2.0)
