ANSI codes instead of colors when pytest imports colorama through conftest.py

[grovduck]

I had reported this as an issue at pytest, but it's probably more likely an issue with colorama. The gist of the issue is that when a user has a custom pytest conftest.py file used which, in turn, imports colorama, the handles dictionary within win32.py does not get reparsed on the second import. I've suggested a possible fix in that ticket, but will defer to your judgment on how best to fix it. Thanks for looking at it.

This is caused by importing colorama with pytest's fd redirection active. I implemented a workaround for this here https://github.com/pytest-dev/pytest/pull/2611.
