Change wpdb query for get_option

[sebastian.pisula]

I think that in wp-includes/functions.php:1362 should be

<?php
$installed = get_option( 'siteurl' );

now is:

<?php
if ( ! wp_installing() ) {
                $alloptions = wp_load_alloptions();
        }
        // If siteurl is not set to autoload, check it specifically
        if ( !isset( $alloptions['siteurl'] ) )
                $installed = $wpdb->get_var( "SELECT option_value FROM $wpdb->options WHERE option_name = 'siteurl'" );
        else
                $installed = $alloptions['siteurl'];
