[Phpunit] AssertEqualsToSameRector fails if markTest* exists in function

Bug Report

Subject	Details
Rector version	Rector 0.9.29
Installed as	prefixed Rector

It seems that the AssertPropertyExistsRector fails if a markTestIncomplete or markTestSkipped is present in the (test) function it tries to refactor. The error is Uncaught Error: Call to a member function getType() on null in <path-to-vendor>/rector/rector-prefixed/rules/phpunit/src/Rector/MethodCall/AssertEqualsToSameRector.php:92 which is the return in this code snippet:

    private function getNodeType(\PhpParser\Node\Expr $expr) : \PHPStan\Type\Type
    {
        /** @var Scope $nodeScope */
        $nodeScope = $expr->getAttribute(\Rector\NodeTypeResolver\Node\AttributeKey::SCOPE);
        return $nodeScope->getType($expr);
    }

Expected Behaviour

No error is thrown, refactor for assertEquals -> assertSame should still be applied

Thank you for your report and demo link!

Could you send a failing test case in a pull-request, so we have it covered in Rector?
Here is step by step tutorial how to add it: https://github.com/rectorphp/rector/blob/master/docs/how_to_add_test_for_rector_rule.md

Changed the title of the issue as I was confusing rectors. Created #5800 for the test fixtures

[Bl00D4NGEL]

Issue fixed with #5800
