\Drupal calls should be avoided in classes, use dependency injection instead

I think that at least some of the failing tests are caused by the following:

+++ b/modules/log/src/Plugin/Field/FieldFormatter/FileUriLinkFormatter.php

+  public function __construct(FileSystemInterface $file_url_generator) {
+    $this->fileUrlGenerator = $file_url_generator;
+  }

The service 'file_url_generator' does probably not implement FileSystemInterface, so an other interface would need to be used here.

+    return new static(
+      $container->get('state'),
+    );
+  }

For classes that are a service, the services it depends on need to be declared in a [module].services.yml file. In this case that would be in "feeds_test_events.services.yml". And the service class should not have a static create() method as above.

I see also some extra returns in the patch file that could be removed.

Thanks for working on this. :)

In FileUriLinkFormatter, I made sure that the parent constructor gets called with the right parameters. Let's see if that makes the tests pass.

I merged the code!
