Allow reset of settings if block_visibility_settings is empty

[jam1e]

During a generic site update, the option block_visibility_settings was emptied (Nothing to do with the block-visibility plugin).

As we had no settings saved, we weren't able to see the block visibility settings within the block editor. I attempted to reset the settings from the plugin settings page, but was unable to do so.

The issue came from the class-block-visibility-reset-settings-controller.php on line 97.

if ( ! get_option( 'block_visibility_settings' ) ) {
	return new WP_Error( '500', $error_message, array( 'status' => 500 ) );
}

if ( isset( $settings['reset'] ) ) {
	if ( 'all' === $settings['reset'] ) {

		// Delete the currently saved settings and pull the defaults.
		delete_option( 'block_visibility_settings' );
		$new_settings = get_option( 'block_visibility_settings' );

		// ...
	}
}

Would it be possible to have the option not required before deleting the option, and then regenerating it?

Sorry if I've worded this terribly.
