The code in upload_file std::move()-s vector of names into
merge_objects() method, then iterates over this vector to delete
objects. The iteration is apparently a no-op on moved-from vector.
The fix is to make merge_objects() helper get vector of names by const
reference -- the method doesn't modify the names collection, the caller
keeps one in stable storage.
