v3 Utils.php civicrm_api3_verify_one_mandatory throws notice error for undefined $keys vairable

If there are no $keyoptions passed into function civicrm_api3_verify_one_mandatory (api/v3/utils.php) then it calls "civicrm_api3_verify_mandatory ($params, $daoName, $keys );" using an undefined variable $keys which in turn throws a notice error about an undefined variable. I also assume that if there are $keyoptions there would also be a notice error because this function is setting the $key value on a nested array ($key[0][]) which isn't declared. My suggestion is to add the following at the beginning on the function:

$keys = array(array());
