I don't think you're supposed to need this. Whenever the file changes
nautilus itself invalidates the file info and re-asks for it. In general
you need only call nautilus_file_info_invalidate_extension_info() when
something happened to the file that nautilus doesn't know about.

However, there might be a bug that makes this not work for the case of
renames.
