Broken behavior for SET in SQL update

[sebastien-gallet]

Regression bug

use Zend\Db\Sql\Sql;
[...]
$sql = new Sql($adapter);
$update = $sql->update();

$data = array(
    'field_a' => true,
    'field_b' => false,
    'field_c' => true,
);

$update
    ->table('test_table')
    ->set($data);
echo $sql->getSqlStringForSqlObject($update) . PHP_EOL; exit;

Up to ZF 2.2.8 the following was properly working and produced the following correct query

UPDATE `test_table` SET `field_a` = '1', `field_b` = '', `field_c` = '1'

But since ZF 2.3.0 (including dev-master), the query generation is broken:

UPDATE `test_table` SET `field_a` = '1'

The list of SET arguments is reduced to anything before the first false value.
