Subject of the issue

I'm trying to replace a previously uploaded qgis project with a new one via administrative interface, but once saved it always shows the previous file.

Steps to reproduce

1. download and unzip G3WSUITE_3.5.zip
2. extract project_data\spatialite folder and upload it as is to server (eg: into \shared-volume\project_data\spatialite)
3. extract projects/building-management-demo.qgs and create a new project via g3w-admin interface
4. save it and re-open the edit page (eg: http://localhost:8000/it/admin/qdjango/buildings/projects/update/public-building-management-demo/)
5. the displayed .qgis project file name should match the following:

6. now extract projects/building-management-demo-2.qgs
7. upload it to the previously created project via g3w-admin interface, saving it and re-opening the edit page (eg: http://localhost:8000/it/admin/qdjango/buildings/projects/update/public-building-management-demo/)
8. the displayed .qgis project file name still match the previous one:

That is: building-management-demo.qgs instead of building-management-demo-2.qgs

Environment

• g3w-admin: 3.5.dev-20230313134606
• g3w-client: 3.8.0-alpha.1
• browser: Firefox 111.0

Additional info

The admin interface does not return any errors (e.g. preventing file saving), below the docker container log at the time of saving:

Logged warning: Loading a file that was saved with a newer version of qgis (saved in 3.26.0-Buenos Aires, loaded in 3.22.16-Białowieża). Problems may occur.
