Title post id 9999 fix (TEC 3.0)

/**
 * Fix for iFeature / CyberChimps themes where a bogus URL like
 * example.com/?post_id=9999 is being displayed above event pages
 * (normally when Default Page Template has been selected).
 *
 * Do not add this to the main theme (in the case of iFeature) but
 * place it within your child theme's functions.php file.
