Using add_imports makes isort unusable

[ziima]

Since the release of isort 5, the add_imports options stopped working.

Let's have a file with only imports:

from __future__ import unicode_literals

from os import path

Running

isort --check-only --diff test.py --add-import 'from __future__ import unicode_literals'

results in

ERROR: /tmp/test/test.py Imports are incorrectly sorted and/or formatted.

with no diff provided.

Thanks for reporting this issue! The combination of checking while adding imports wasn't previously tested. I've fixed the issue in 5.0.5 and added an additional regression test to ensure it doesn't resurface.

Thanks!

I confirm it works with 5.0.5. Thanks
