Remove the 'default' textdomain on __() translation functions introduced into script-loader.php for 5.0

[garrett-eclipse]

Found in the 5.0 branch in the /wp-includes/script-loader.php is the use of 'default' as the textdomain for the () translation functions;

<?php
                                                        'future' => __( '%s from now', 'default' ),
                                                        /* translators: %s: duration */
                                                        'past'   => __( '%s ago', 'default' ),
                                                ),
                                        ),
                                        'formats'  => array(
                                                'time'                => get_option( 'time_format', __( 'g:i a', 'default' ) ),
                                                'date'                => get_option( 'date_format', __( 'F j, Y', 'default' ) ),
                                                'datetime'            => __( 'F j, Y g:i a', 'default' ),
                                                'datetimeAbbreviated' => __( 'M j, Y g:i a', 'default' ),

These should be removed as unnecessary.
