fix: run router test with runTestsInSeparateProcesses

The router uses include_once to load route definitions from the apps.

First include_once for apps/files/appinfo/routes.php returns the expected array.

Second include_once returns true, because the file was already included.

To workaround the tests must run in a separate process.
