Stop fallback for empty local path in ui::SelectedFileInfo's constructor.
Previously ui::SelectedFileInfo's constructor has a fallback to use the file
path instead of an emtpy local path. But this fallback can assign non-native
paths like '/special/drive/xxx' to local_path variable when the file does not
have a snapshot.
The CL removes the fallback, and modify the default behavior of
FileSelectDialog::Lister so that it routes an empty local_path to file_path.
