print_config does not work in Python 3.8

[ZhuBaohe]

I follow the example of Sacred 0.8.1 Documentation in python 3.8.5:

from sacred import Experiment

ex = Experiment('hello_config')

@ex.config
def my_config():
    recipient = "world"
    message = "Hello %s!" % recipient

@ex.automain
def my_main(message):
    print(message)

When I run the code, an exception is thrown:

$ python hello_config.py print_config
INFO - hello_config - Running command 'print_config'
INFO - hello_config - Started
ERROR - hello_config - Failed after 0:00:00!
Exception originated from within Sacred.
Traceback (most recent calls):
  File "D:\anaconda3\envs\nlp\lib\site-packages\sacred\commands.py", line 61, in _non_unicode_repr
    repr_string, isreadable, isrecursive = pprint._safe_repr(
TypeError: _safe_repr() missing 1 required positional argument: 'sort_dicts'

This is already fixed on the master (#763, #719). I hope to get to creating a release that can be pushed to pypi soon.

I'll close this since it is fixed in sacred 0.8.2
