refs: pass NULL to refs_read_ref_full() because object ID is not needed

refs_read_ref_full() wraps refs_resolve_ref_unsafe(), which handles a NULL oid pointer of callers not interested in the resolved object ID. Pass NULL from files_copy_or_rename_ref() to clarify that it is one such caller. Signed-off-by: René Scharfe <l.s.r@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
