"Especially in production it is sometimes critical to know exactly when your cache is cleared or warmed up. Currently cache:clear provides no feedback whats however. As sites get bigger, so become their cache files. Removing old cache files may sometimes even take minutes. Without any feedback from the cache:clear you do not know the current status.

That's why i added more feedback to the cache:clear command that it makes it possible to see when your cache is warmed up and ready to go."

[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.
