This PR removes some useless code after #16024.

**1.** [ConstraintValidator::buildViolation()](https://github.com/symfony/symfony/blob/2.8/src/Symfony/Component/Validator/ConstraintValidator.php#L64) marked as deprecated in [2.8](https://github.com/symfony/symfony/blob/2.8/src/Symfony/Component/Validator/ConstraintValidator.php#L64), and has been removed in [3.0](https://github.com/symfony/symfony/blob/3.0/src/Symfony/Component/Validator/ConstraintValidator.php#L51).

But all the ```Symfony/Component/Validator/Constraints/*```validators still making calls to this parent method.

**2.** Correct me if I'm wrong, but this condition:
```php
$this->context instanceof ExecutionContextInterface
```
in the ```Symfony/Component/Validator/Constraints/*``` validators is useless since 3.0, because the ```$context``` can only be ```ExecutionContextInterface```. I guess the porpuse of this condition was, that in 2.8 there was a [legacy interface](https://github.com/symfony/symfony/blob/2.8/src/Symfony/Component/Validator/Context/ExecutionContextInterface.php#L63) too.

And AFAIK, the ```$context``` is [always initialized](https://github.com/symfony/symfony/blob/3.0/src/Symfony/Component/Validator/Validator/RecursiveContextualValidator.php#L842) before validation, so no need to check that ```$context``` is whether null or not.

**3.** The return value of [ExecutionContextInterface::getViolations()](https://github.com/symfony/symfony/blob/3.0/src/Symfony/Component/Validator/Context/ExecutionContextInterface.php#L239), is in a different namespace, so it should be used.
