Duplicate output in log file

Rasa version: 1.1.8, commit e3ae94995d

Python version: 3.7 (I have to check once I get home)

Operating system (windows, osx, …): Observed on Ubuntu and Mac OS X

Issue: Both rasa train and rasa test tend to write output twice for no reason. This happens on my Ubuntu desktop and on Vova’s MacBook, but not on my MacBook.

Error (including full traceback): There is no error message generated. Here are a few lines of example output:
