Fatal error __clone method called on non-object in Drupal\Core\Routing\UrlGenerator->getRoute
when $name = ''
Function expects to throw specific error instead:
```
@throws \Symfony\Component\Routing\Exception\RouteNotFoundException
```
For me it was using drush uli to login after pulling DB down, the language `en` was not available due to config split.
So "" isn't a loadable route. We need better steps to reproduce.
Do not clone if route isn't an object.

Thanks for reporting!
Believe we will need a test case to show this problem.
Changes are made on on 11.x (our main development branch) first, and are then back ported as needed according to the Core change policies → .
