Fatal error: Uncaught Error: Class "Drupal\language\Config\LanguageConfigOverrideEvents" not found

Problem/Motivation

The event subscriber \Drupal\parameters\EventSubscriber\ParametersConfigOverrideSubscriber::getSubscribedEvents uses the class LanguageConfigOverrideEvents which may not be available if the language module is not installed.

Proposed resolution

The subscribed may have to check first, if that class exists.
