Comment:

 OK, that was hard. Unit tests for theme switch in Customizer have been
 added.

 Additional changes:

 * Use object cache instead of static var for
 `WP_Theme::get_allowed_on_network()` and
 `WP_Theme::get_allowed_on_site()`. This allows unit test to update the
 allowed themes.
 * Include `$_REQUEST` in `WP_UnitTestCase::clean_up_global_scope()`
 * Add `test_override_sidebars_widgets_for_theme_switch` and
 `test_override_sidebars_widgets_for_non_theme_switch`
 * Add `$options` param to `WP_Customize_Manager::save()` to bypass Ajax-
 specific behaviors
 * Introduce new `customize_save_before_switch_theme` action instead of
 having WP look at Ajax-specific action `wp_ajax_customize_save`
 * Test saving the customizer and ensuring the new theme and old theme have
 expected states
