* @param NodeTranslation $translation The node translation

*
* A function that checks the URL and sees if it's unique.
* It's allowed to be the same when the node is a StructureNode.
* When a node is deleted it needs to be ignored in the check.
* Offline nodes need to be included as well.
*
* It sluggifies the slug, updates the URL
* and checks all existing NodeTranslations ([1]), excluding itself. If a URL existsthat has the same url.
* If an existing one is found the slug is modified, the URL is updated and the check is repeated
* until no prior urls exist.
*
* NOTE: We need a way to tell if the slug has been modified or not.
* NOTE: Would be cool if we could increment a number after the slug. Like check if it matches -v#
* and increment the number.
*
* [1] For all languages for now. The issue is that we need a way to know if a node's URL is prepended with the
* language or not. For now both scenarios are possible so we check for all languages.
*
* @param NodeTranslation &$translation Reference to the NodeTranslation. This is modified in place.
* @param EntityManager $em The entity manager
* @param array $flashes The flash messages array
