UnitTests are failing

If I run Redirect's unit tests locally, I get 6 failures:

<snip>
6) Drupal\Tests\redirect\Unit\EventSubscriber\RouteNormalizerRequestSubscriberTest::testOnKernelRequestRedirect with data set #2 ('https://example.com/index.php/', array('node/1'), 'https://example.com/?q=node/1', true)
Argument 2 passed to Drupal\Tests\redirect\Unit\EventSubscriber\RouteNormalizerRequestSubscriberTest::getGetResponseEventStub() must be of the type array, string given, called in /redirect/tests/src/Unit/RouteNormalizerRequestSubscriberTest.php on line 84 and defined

The signature for \Drupal\Tests\redirect\Unit\EventSubscriber\RouteNormalizerRequestSubscriberTest::getGetResponseEventStub() has the second parameter, $query_string, incorrectly typed as array. Seems to have been introduced by #2854462: Needs tests: Disable route normalizer for core routes..
