When passing a tag as the first argument to `git replace --graft`, it can be useful to accept it and use the underlying commit as a the commit that will be replaced. This already works for lightweight tags, but unfortunately for annotated tags we have been using the hash of the tag object instead of the hash of the underlying commit. Especially we would pass the hash of the tag object to replace_object_oid() where we would likely fail with an error like: "error: Objects must be of the same type. 'annotated_replaced_object' points to a replaced object of type 'tag' while 'replacement' points to a replacement object of type 'commit'." This patch fixes that by using the hash of the underlying commit when an annotated tag is passed.
