The old `create_dir_entry()` took a `files_ref_store` as its first parameter, because that is what needed to be stored into the old `dir_entry` struct. The new version takes a `ref_cache`, because that is what the new `dir_entry` struct requires. This hunk is a logical consequence of that change.

I'll improve the commit message to explain this better.

Thanks, Michael
