Bug in the backend if I broke up an action

} while ($objGroup->pid);

Hi, I found some Issue and have a fix for that:

`// Generate groups
do {
$objGroup = Group::findByPk($intPid);

        if (null !== $objGroup && $objGroup->id && $objGroup->name) {
            $arrGroups[] = array('id' => $objGroup->id, 'name' => $objGroup->name);

            if ($objGroup->pid) {
                // Do not show the mounted groups
                if (!$objUser->isAdmin && $objUser->hasAccess($objGroup->id, 'iso_groups')) {
                    break;
                }

                $intPid = $objGroup->pid;
            }
        } else {
            // Kein gültiger Eintrag gefunden
            break;
        }
    } while ($objGroup->pid);`

Sorry, detailed Description is missing at this issue. I created a new productgroup, put a product in it and deleted the productgroup. Then I get a Error which referenced the line. The Error comes because there was no questiion about the $objGroup is null. So I fixed it.

Shouldn't we un-assign all products from a group if the group is deleted? Then the error wouldn't happen in the first place?
