Description

It should update the wiki repository remote origin while update the repository mirror address.
Below is the source code of save mirror address, I think update the wiki repository remote origin is missing.

// SaveAddress writes new address to Git repository config.
func SaveAddress(m *models.Mirror, addr string) error {
	repoPath := m.Repo.RepoPath()
	// Remove old origin
	_, err := git.NewCommand("remote", "rm", "origin").RunInDir(repoPath)
	if err != nil && !strings.HasPrefix(err.Error(), "exit status 128 - fatal: No such remote ") {
		return err
	}

	_, err = git.NewCommand("remote", "add", "origin", "--mirror=fetch", addr).RunInDir(repoPath)
	return err
}
