Please fix your software not to ping master

You may be unaware but you're running some software that meddles with every commit on https://github.com/huggingface/transformers/

Something is wrong with the software you're using. It adds a reference to almost every PR in the master tree. Which is very wrong. Please check your software and please don't do it again.
