[Validation] Fixed IdentityTranslator to pass correct Locale to MessageSelector

This PR fixes the following case:

```php
\Locale::setDefault('en');
$translator = new IdentityTranslator(new MessageSelector());

echo $translator->transChoice('There is one apple|There are %count% apples', 10, array('%count' => 10));
```

Result before PR:

```
There are 1 apples
```

Result after PR:

```
There is one apple
```

The reason for the current behavior is that the locale `null` is passed to `MessageSelector`, but `MessageSelector` is not programmed to accept `null` values.

[MonologBridge] Allow SwiftMailerHandler to listen to kernel.terminate.event

This PR accompanies symfony/MonologBundle#51. Both are intended to fix symfony/symfony-standard#425.

MonologBundle configures SwiftMailerHandler as a Monolog handler and injects the proper transport service.
