[Interchange][FBX] Issue with asset name clashes after auto import

The mesh changes and the asset name stays the same while the two FBX are completly different: different filename, different mesh names in the FBX

With Interchange

1) Copy an fbx file in the windows explorer so UE triggers an auto import

2) Perform the import

3) now drag and drop a new fbx in the same folder. UE says the asset already exists and will replace it.
