In #3470 we changed the search_api_language filter to a language_with_fallback filter to ensure that users could find matching content in different languages if no version in their own language was available. However, this also changed the IDs of the filter which can break existing sites that might rely on that filter.
In this commit we revert the ID/name change and only change the field used. We also revert any formatting changes made to the views.* files to make fixing merge conflicts in our search rework easier.
