Initial work on moving creation of language to translation manager

[oxisto]

This PR is the start of the epic #2108. The first step is that we need to create our Language node in the translation manager (or in this case the translation context) instead of the config, so we can already set the correct context.

LGTM, I can imagine though that we have to be careful with the EmptyTranslationContext, and for the Language holding it not being used.

Yes the EmptyTranslationContext is a ugly workaround that is hopefully gone once the ctx stuff is fully implemented.
