9714cfc Fixes fatal error when intl module is not installed.

Discussion
----------

Session instantiation breaks with Fatal error if intl module is not installed.

A check for class_exists in setPhpDefaultLocale() fixes this, though I got the feeling it should be resolved with a proxy or subscriber object; setPhpDefaultLocale feels like a hack now.

Locale::setDefault don't throw any exception
Maybe just :

```php
if (class_exists('Locale', false)) {
    return \Locale::setDefault($this->locale);
} else {
    return false;
}
```
