Remove some options from scrubbing that are needed on WordPress.com

Changes proposed in this PR

• Remove Jetpack options from scrubbing that are needed for an active Jetpack connection on WordPress.com, because staging sites don't work on WP.com without Jetpack

I haven't tested this, but a couple things:

1. You'll need to return the array after removing the options
2. You can simplify the code a bit by using array_diff

So something like this:

/**
 * Remove some options from scrubbing that are needed on WordPress.com.
 *
 * @param array $options_to_clear Options to clear.
 *
 * @return array Modified options to clear.
 */
function safety_net_scrub_options_wpcom( $options_to_clear ) {
	if ( defined( 'IS_WPCOM' ) && IS_WPCOM ) {
		$unset_wpcom_options = array( 'jetpack_private_options', 'jetpack_secrets' );
		$options_to_clear = array_diff( $options_to_clear, $unset_wpcom_options );
	}

	return $options_to_clear;
}
add_filter( 'safety_net_options_to_clear', 'safety_net_scrub_options_wpcom' );
