WP Upgrader: update_bulk_plugins_complete_actions and update_bulk_theme_complete_actions should pass information about all plugins/themes to the filter

[ragulka]

In class-wp-upgrader.php, line 1214 there is this line:

$update_actions = apply_filters('update_plugin_complete_actions', $update_actions, $this->plugin);

When adding a filter to it like this:

add_filter('update_bulk_plugins_complete_actions','test_filter',99,2);

function test_filter( $update_actions, $plugins ) {
    echo print_r( $plugins, 1);
    return $update_actions;
}

Only the last updated plugin info will be printed. However, it should contain information about all the plugins that were updated (since we are dealing with a bulk upgrade here).

The same applies to update_bulk_theme_complete_actions

Confirmed. The actions were added in [14879] (for #11232).
