ignore FutureWarning in tests
As discussed in https://github.com/huggingface/transformers/pull/7033 we can't deal with transformers' `FutureWarning` in tests, since we have to keep those tests around until they become normal warnings and then the tests will get fixed/adjusted. So currently they just generate noise that can't be acted upon.

The only side-effect I can see is with other libraries' FutureWarnings, which now will be silenced too, but again we can easily fix those as soon as those aren't futuristic any more.




Yes, I agree with this. Thanks @stas00!
