Problem/Motivation
If you install standard you will watchdog entries on every request:
Theme hook toolbar_item not found.
This was caused by a "merge conflict" between:
#2226207: Make 'template' the default output option for hook_theme()
diff --git a/core/modules/toolbar/toolbar.module b/core/modules/toolbar/toolbar.module

- $items['toolbar_item'] = array(

return $items;
}and #2326895: Convert toolbar_element_info() to Element classes
Proposed resolution
Drop the line: '#theme' => 'toolbar_item',from ToolbarItem.
