Fails to register plugins in Smarty3

Fatal error: "Plugin 'crmSQL' not callable"SmartyException: "Plugin 'crmSQL' not callable"

This is because, as of 5.70.1 CRM_Core_SmartyCompatibility::register_function maps this call to

parent::registerPlugin('function', $function, $function, $cacheable, $cache_attrs);

note that it passes $function in twice. So it thinks crmSQL is the callable, which it isn't.
