Fixing tests. It seems master changed something in the warnings.
Author: Narsil
Pull request: yes

# What does this PR do?

Trying to keep warning tests for now. Should be discarded if it becomes
too hard to maintain.

60 started to trigger a new warning, saying that the input_ids length was longer than model max_length.
I'm not really sure which commit triggered this, but it did not occur in the original PR

Comments:
I don't understand this: `"60 started to trigger a new warning, saying that the input_ids length was longer than model max_length."`

Would be nice to find what triggered this to be sure we didn't introduce a bug no?

@patrickvonplaten I think we're good.

It's this commit 79bbcc5260c3acde3e7156966ba836afcbfd8808 that triggered the extra warning.
