largefiles: fix explicit commit of normal/largefile switch
Commit of corresponding normal/largefiles pairs would only commit the standin.
That is usually fine, except if either the normal file or the standin is a
remove while the other is an add. In that case it would either give duplicate
colliding entries or lose the file.
Instead, commit both filenames if one of them is a remove.
