Fix flake8

[sentrivana]

Tiny PR with some flake8 fixes:

• some extra imports
• testing a removed util

• ignoring sentry_sdk/integrations/aiohttp.py:393:33: E231 missing whitespace after ':' on this line

  url = f"{request.scheme}://{request.host}{request.path}"

  🙄

Original output:

linters: commands[0]> flake8 tests sentry_sdk
tests/test_utils.py:109:12: F821 undefined name 'datetime_from_isoformat'
