PHP errors when no Primary Category selected in WP_DEBUG===true

If there is no primary category selected a PHP error is thrown.
If the category does not have an index of [0] but instead has and index of [1] then it does not work correctly.

Solution? Change from

if ( ! is_wp_error( $terms ) && ( is_array( $terms ) && $terms !== array() ) ) {
$this->og_tag( 'article:section', $terms[0]->name );

To:

if ( ! is_wp_error( $terms ) && ( is_array( $terms ) && ! empty( $terms ) ) ) {
$this->og_tag( 'article:section', reset($terms)->name );
