Remove WP Shortlink

For some odd reason wp.me is redirecting back to an old domain that was changed 5 months ago and is expired. I checked in my database on myPHPadmin and wp-config and they both have the current url.

remove_action( ‘wp_head’, ‘wp_shortlink_wp_head’);

Nothing happened, so I altered it a bit to this

remove_action( 'wp_head', 'wp_shortlink_wp_head', 10, 0 ); // removing the default shortlink
add_action( 'wp_head', 'bilty_shortlink_head'); // adding the new bit.ly shortlink

function bilty_shortlink_head() {
	global $post;
	$shortURL = get_post_meta($post->ID, 'bitlyURL', true);
	if(!empty($shortURL)) {
		echo '<link rel="shortlink" href="'.$shortURL.'" />'."\n";
	} else {
		echo '<link rel="shortlink" href="'.get_bloginfo('url').'?p='.$post->ID.'" />'."\n";
	}
}

With no success in removing wp.me. Has anyone found success in removing it?
