Description
When applying Microsoft Windows policies with lgpo.set sometimes a KeyError will occur.

Ex:

[ERROR   ] An exception occurred in this state: Traceback (most recent call last):
  File "c:\salt\bin\lib\site-packages\salt-3002.7-py3.7.egg\salt\state.py", line 2154, in call

  File "c:\salt\bin\lib\site-packages\salt-3002.7-py3.7.egg\salt\loader.py", line 2106, in wrapper
    return f(*args, **kwargs)
  File "c:\salt\bin\lib\site-packages\salt-3002.7-py3.7.egg\salt\states\win_lgpo.py", line 410, in set_
    return_value_only=True,
