Fixed the third argument in VarDumperTestTrait.

[adrozdek]

In VarDumperTestTrait's asserts the third argument is called $filter and by default it should be equal to 0.
Right now it's called $context or $format and is set to null. Also $data argument is called $format sometimes.

public function assertDumpEquals($expected, $data, $filter = 0, $message = '')
public function assertDumpMatchesFormat($expected, $data, $filter = 0, $message = '') -

This rule is in Symfony 4.0 set. You address Symfony 4.4

When was this changed? Link to UPGRADE.md or PR in Symfony is needed. Maybe we need new rules to Symfony 4.4, we cannot change old ones

[adrozdek]

Sorry for giving 4.4 version but this parameter is the same for 4.0: https://github.com/symfony/symfony/blob/4.0/src/Symfony/Component/VarDumper/Test/VarDumperTestTrait.php
The UPGRADE-4.0.md for VarDumper is wrong. I created PR for changing that: symfony/symfony#33821

The description is wrong but the example taken from code is correct:

I see, thanks for clarification
