Presenter::$invalidLinkMode is silent by default and can't be overwritten by config

[forgie1]

Version: 3.2.6

Bug Description

This commit broke it: 244fc48
Because of condition here: https://github.com/nette/application/blob/v3.2.6/src/Bridges/ApplicationDI/PresenterFactoryCallback.php#L58
Link mode keeps being set to 0.

So no warning is thrown that link is broken.

$presenter instanceof Nette\Application\UI\Presenter && !isset($presenter->invalidLinkMode
As the problem
