Fix tests for windows, which appears to have a lower resolution time

[sfider]

Tests have around 19 fails when run on windows. Mostly OSError: [Errno 22] Invalid argument on 4000 timestamps (too low resolution time).

test_push also had issues with recorded times comparing as equal (again, low resolution time). But I also noticed it used arrow.now() while tested code uses arrow.utcnow(), so I fixed this as well.

Thank you for fixing this. Could you fix the linting issues? Then this would look good to go from my side.

Sorry, I was going to, but I'm really swamped with work. I would have to figure out how to run lint test locally not to push something that would fail again XD

I'll try to get to it on the weekend maybe.

No worries and no rush. This is the command we run in the CI:

flake8 --show-source watson/ tests/ scripts/

Thanks @sfider!
