Shortcode with tesimonial id need query reset

I am using shortcode with single testimonial ID. After that I have a code another custom query. But, shortcode query cause issue to another next as there is no reset code added after calling single post query after line#461 in tb-testimonials.php.

else # single testimonial
{
if( ! is_numeric( $id ) ) return;

	$q = new WP_Query( array( 'p' => $id, 'post_type' => $this->post_type, 'post_status' => 'publish' ) );
	if( $q->have_posts() )
	{
		$return = '';
		while( $q->have_posts() )
		{
			$q->the_post();
			$return .= $this->prepare_testimonial( is_null( $template ) ? 'shortcode' : $template );
		}
		wp_reset_query(); // This reset is required.
		return $return;
	}
	else
		return;
}
