When writing

class A {
  /**
   * @throws \LogicException
   *
   * @return void
   **/
  public method foo()
  {
    throw \LogicException();
  }
}

class B extends A {
  /**
   * @return void
   **/
  public method foo()
  {
    return;
  }
}

Phpstan is now merging the phpdoc and think that B::foo is returning an exception which is not true.

This has multiple bad effects on https://packagist.org/packages/pepakriz/phpstan-exception-rules
since it now report false positive Unused exception or You didn't try/catch a possible exception.
