git-fetch: ignore dereferenced tags in expand_refs_wildcard

There was a little bug in the brace expansion which should remove
the ^{} from the tagname. It used ${name#'^{}'} instead of $(name%'^{}'},
the difference is that '#' will remove the given pattern only from the
beginning of a string and '%' only from the end of a string.
