ZF-12534: rerouting feature broken on region translations en_GB

Description

The Adapter has a feature to check for rerouting if possible ie.

messageId = 'Foobar' and i want to translate into en_GB but its not available in en_GB i can configure route en_GB -> de_DE this doesnt works anymore because there is a case where the adapter try to check if not found also for the language itself (en_GB -> en) this causes an issue where the routing mechanism doenst work anymore. I will provide a fix for this issue
