Jetpack: Search: If filter has no name, don't show heading

[ebinnion]

Currently, if a filter doesn't have an actual name, we set it to a key that we used to generate the ES aggs. Let's not do that.

Rather than not displaying it, why not pull it from the registration?

$taxonomy = get_taxonomy( $tax_slug );
echo esc_html( $taxonomy->labels->name );

ahh, Ahh, I dig that. So, for:

• "post_type" filters, we'd just use __( 'Post Type', 'jetpack' )
• "date_histogram", we'd use something like "Posts by month", "Post by year", etc.
• "taxonomy", we'd use the taxonomy name
