Copying Record with TCEMain processCmdMap throws sql errors on pages with f.e. sys_template or sys_domain records.

Reproduce:

Put this in the constructor of f.e. your backend.php and replace the first number with the id of a page that has one of the mentioned records, and the second one with the target page:

$tce = t3lib_div::makeInstance('t3lib_TCEmain');
    $cmd['pages'][41]['copy'] = 42;
    $tce->start(array(),$cmd);
    if($cmd) {
        $tce->process_cmdmap();
    }
