[Form] Update UPGRADE-2.3.md to account for #9388

Added documentation for how to correctly pre-fill a form using the form's `data` option.
The "old" and also wrong way of doing it broke with Symfony 2.3.7 (with https://github.com/symfony/symfony/pull/9388 to be precise) and this short documentation should help others to fix the problem and do it right.

When you use ts files, QtLinguist, generate empty string for all translations, even if there are not translated yet.

It could be a good idea to generate an entry in the MessageCatalogue only if translation value is not empty.

[Twig Bridge] Fixed bug in ExpressionExtension

Currently it's impossible to use the expression extension in Twig as the <code> ExpressionExtension ::createExpression</code> method is defined as private which will throw an exception: <code>Fatal error: Call to private method Symfony\Bridge\Twig\Extension\ExpressionExtension::createExpression() from context '__TwigTemplate_83f94baa63f1faa30cdacee32980572936c887ef25baa389ebddd7a666db3a9b'</code>
