remote: fix leaking peer ref when expanding refmap
When expanding remote refs via the refspec in `get_expanded_map()`, we first copy the remote ref and then override its peer ref with the expanded name. This may cause a memory leak though in case the peer ref is already set, as this field is being copied by `copy_ref()`, as well. Fix the leak by freeing the peer ref before we re-assign the field.
