Uncaught Error in widgets.php

Hello,

On our site, there were several of our product categories where only have of the page was rendered. Looking at the error logs, it appeared to come from the get_attribute_values (line 409) function. Some of the times when it was called, a WP_Error object would be returned from the get_terms() (line 423) functions however there was no check in place for this, causing a fatal error to happen when the object was passed as an argument to the function wp_list_pluck method (line 462). On our site we resolved this by adding the following check on line 424:

if(is_a($re, 'WP_Error')) return array();

I made the post so that a better fix might be found and added to the plugin itself.

WordPress Version: 4.7.5
AJAX Product Filter Version: 1.1.8.1
WooCommerce Version: 3.0.7
