Gravatar requests are not blocked in comments list table

[ocean90]

When Gravatar requests are blocked the default mystery image in the comments list table is still requested from gravatar.com.

It looks like this is caused by get_avatar( $comment, 32, 'mystery' ); in WP_Comments_List_Table::floated_admin_avatar(). Removing the mystery default loads the local image.

Workaround/Fix:

/**
 * Overrides any custom default value with the one set in the settings.
 *
 * @param array $args Arguments passed to get_avatar_data(), after processing.
 * @return $array Filtered arguments.
 * */
function ds_force_avatar_default( $args ) {
	$args['default'] = get_option( 'avatar_default', 'mystery' );
	return $args;
}
add_filter( 'pre_get_avatar_data', 'ds_force_avatar_default' );

🤦‍♂️ it appears this feature is simply not working as intended anymore.

When selected, even picking the "Blank" still makes requests out to Gravatar.com.

Also, it is possible to have a Gravatar value selected, say... "Retro", then turn it on, and end up with a faulty value:

Moving this to the 2.0.0 milestone to work on it asap.
