Error on startup of fresh clone

In bash:

git clone git@gitlab.com:PushFish/PushFish-API.git
cd PushFish-API
# load your dev environment. In my case, virtualenvwrapper
workon pushfish
./application.py

Output:

Traceback (most recent call last):
  File "./application.py", line 14, in <module>
    cfg = Config(create=True)
  File "/pushfish/pushfish-api/PushFish-API/config.py", line 155, in __init__
    write_default_config(path=path, overwrite=False)
  File "/pushfish/pushfish-api/PushFish-API/config.py", line 113, in write_default_config
    os.mkdir(cfgdir)
FileNotFoundError: [Errno 2] No such file or directory: '/home/[username]/.config/pushfish-api'

In my opinion, this is bad behavior. It should work out of the box. If the environment variable is not set, it should default to the current directory.
