Fix tests with nette/component-model 3.1.0

[jtojnar]

Container::getComponents() returns array when $deep is false:
nette/component-model@7f613ee

There is still breakage from nette/application@bb8f93c in webchemistry/testing-helpers. It can be fixed with the following patch but there are other issues with it and the repo looks dead so not sure if it makes sense trying to track them down:

--- a/src/Components/Presenter.php
+++ b/src/Components/Presenter.php
@@ -31,7 +31,7 @@ class Presenter {
 
 			$request = new Request(new UrlScript('http://localhost/'));
 			$presenter->injectPrimary(
-				null, null, new RouterStub(), $request, new Response(), null,
+				$request, new Response(), null, new RouterStub(), null,
 				null, $this->createTemplateFactory($request)
 			);
 		}

Maybe we could apply it with composer-patches plug-in.

Edit: Opened #96
