Revert "Add test setting the locale."

This reverts commit 9cdc3343ff.

Reason for revert: For some reason, Windows kokoro bots are now taking objection to this test.

Original change's description:
> Add test setting the locale.
>
> This CL adds a test which sets the locale to one which uses `1,00`
> instead of `1.00`. This ensures the float emission will get the right
> format.
>
> Bug: tint:1686
