Bug: "Error in atexit._run_exitfuncs" when running unit tests

See original GitHub issue

Description

I’m using the package within a download function like so:

def download(url):
  spinner = Halo(text='Downloading', spinner='dots12')
  spinner.start()
  (...)
  spinner.succeed('Download Complete')
  spinner.stop()

While, the package works as expected when running the program, when running unit test with pytest the test output is followed by the error message pasted below.

System settings

Operating System: macOS
Terminal in use: iTerm2
Python version: 3.5, 3.6, 3.7
Halo version: 0.0.17
pip freeze output:

Expected behaviour

I wouldn’t expect the package to have any impact on these tests that isn’t present when running the program.

Steps to recreate

Run pytest unit tests on a program that uses halo as shown above

“Better” in what sense? If the intent of the atexit handler is to cleanup something, and it’s already cleaned up, is there anything else to do?
