ResultCacheStatement::fetchAll() doesn't respect fetch mode on subsequent calls

Bug Report

Q	A
BC Break	no
Version	2.10.2

When a cached result set is used with fetchAll() and the fetch mode is different from the one used to populate the cache, the original fetch mode is used instead.

$conn = DriverManager::getConnection([
    'driver' => 'pdo_mysql',
    'user'   => 'root',
    'dbname' => 'mysql',
]);

$conn->getConfiguration()
    ->setResultCacheImpl(new ArrayCache());

$qcp = new QueryCacheProfile(0, 'test');

$stmt = $conn->executeQuery("SELECT 'foo' bar", [], [], $qcp);
$stmt->fetchAll(FetchMode::NUMERIC);
$stmt->closeCursor();

$stmt = $conn->executeQuery("SELECT 'foo' bar", [], [], $qcp);
var_dump($stmt->fetchAll(FetchMode::ASSOCIATIVE));

Current behaviour

array(1) {
  [0] =>
  array(1) {
    [0] =>
    string(3) "foo"
  }
}

Expected behaviour

array(1) {
  [0] =>
  array(1) {
    'bar' =>
    string(3) "foo"
  }
}

Closing as fixed by #4034.
