Subtle bug in if-menu.php, with fix

The is a subtle bug that throws errors when WP_DEBUG is set to true that it would be great if you can fix. Here is a fix:

foreach ( $conditions as $condition ) {
	if ( isset( $condition[ 'id' ] ) ) {
		$c2[ $condition[ 'id' ] ]   = $condition;
	}
	if ( isset( $condition[ 'name' ] ) ) {
		$c2[ $condition[ 'name' ] ] = $condition;
	}
	if ( isset( $condition[ 'alias' ] ) ) {
		$c2[ $condition[ 'alias' ] ] = $condition;
	}
}
