/**
 * Temporary function to work around the default widgets that get added to
 * Header Right when switching themes.
 *
 * The $defaults array contains a list of the IDs of the widgets that are added
 * to the first sidebar in a new default install. If this exactly matches the
 * widgets in Header Right after switching themes, then they are removed.
 *
 * This works around a perceived WP problem for new installs.
 *
 * If a user amends the list of widgets in the first sidebar before switching to
 * a Genesis child theme, then this function won't do anything.
 *
 * @since 1.8.0
 *
 * @return null Return early if not just switched to a new theme.
