[Bugfix] Trying to get property of non-object

I have a bugfix request for this plugin. Although the code still works, whenever submitting a form or viewing form entries with this plugin enabled, I get a large number of PHP Notices, reading:

Notice: Trying to get property of non-object in /var/www/html/contact/wp-content/plugins/gravitate-encryption/gds_encryption.php on line 679

This is easily fixed by inserting an if statement around line 679 as follows:

if (isset($detail->id))
{
    $long = $wpdb->get_row($wpdb->prepare("SELECT value FROM ".$wpdb->prefix."rg_lead_detail_long WHERE <code>lead_detail_id</code> = %d", $detail->id));
}

It would be great to see this pushed into the main code branch.
