    Set default columns in ext-list

    Previously ext-list does not inherits ListCommand base class for listing
    and cannot specify columns to display. This commit changes ext-list to
    use ListCommand and adds a unit test for extensions.

    This also changes the default value of _formatters in ListCommand to {}.
    By this subclasses no longer override _formatters unless required.

    Fixes bug 1161866
