Fix T98201: Corrution of filepaths in some case during 'make relative' process.
We need to ensure `Main.filepath` is consistent with the current path
where we are saving the .blend file, otherwise some path processing code
can produce invalid results (happens with e.g. the code syncing the two
path storages in Library IDs).
