Calling stmt_store_result when in the middle of manual fetch cycle should throw an OOS error. However, mysqlnd sets the error in conn property which means mysqli will not throw it. 

Test script:

$mysqli = new mysqli('localhost', 'user', 'password', 'test');
$mysqli->set_charset('utf8mb4'); // always set the charset

$statement = $mysqli->prepare("SELECT b FROM a");
var_dump($mysqli->error, $statement->error);
echo $statement->num_rows();

Expected result:
Fatal error: Uncaught mysqli_sql_exception: Commands out of sync; you can't run this command now

Actual result:
string(52) "Commands out of sync; you can't run this command now"
string(0) ""
