[PHPUnit60] Remove addToAssertionCount() calls in AddDoesNotPerformAssertionToNonAssertingTestRector

[TomasVotruba]

Once the @doesNotPerformAssertions annotation is added, any $this->addToAssertionCount(1); call in that method is dead weight - it only existed to fake an assertion so the test would not be reported as risky. The rule now removes those calls, including a trailing same-line comment.

 class SomeTest extends TestCase
{
+ /**+ * @doesNotPerformAssertions+ */
public function test()
{
$this->someMethodCall();
-- $this->addToAssertionCount(1); // Verify that no exception is thrown
}
}

Nested calls are handled too, e.g. inside try/catch blocks. Methods that do contain a real assertion are skipped as before, so their addToAssertionCount() calls stay untouched.
