Ben Konyi d7ccc3ca6a Revert "Fix orphaned files in tests/language/ and tests/language_2/."
This reverts commit 1989b7f376.

Reason for revert: Bots are sad, red, and purple

Original change's description:
> Fix orphaned files in tests/language/ and tests/language_2/.
>
> Some of these should be tests but were missing "_test". Others seemed
> to simply be dead code. Some should have been referenced but there were
> mistakes in the imports in other files.
