[Doctrine Bridge][Validator] Fix for null values in assosiated properties when using UniqueEntityValidator

This fixes issue with UniqueEntityValidator when ignoreNull = false and associated property contains null value:
```
Warning: ReflectionProperty::getValue() expects parameter 1 to be object, null given in [...]/symfony2/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataInfo.php line 670
```

Here's what docs say about ignoreNull:

> If this option is set to true, then the constraint will allow multiple entities to have a null value for a field without failing validation. If set to false, only one null value is allowed - if a second entity also has a null value, validation would fail.

this replaces #9997 with a proper fix: fixing the cause of the issue instead of adding workarounds for it

"php -r" does not seem to behave properly in HHVM, so the check to detect HHVM has been switch to a check on the environment variable set by Travis.

The only failures in the Console testsuite were due to facebook/hhvm#1327, and a workaround for this issue is easy.

This PR currently includes #9999 in it, to have a working HHVM build on Travis.

[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>
