Possible issue in tests

[goetzk]

Describe the bug

Several recent pulls seem to be failing with BLK100

4s
Run flake8
./pyinfra/operations/opkg.py:2:1: BLK100 Black would make changes.
Error: Process completed with exit code 1.

None of the PRs in question changed that file so they probably shouldn’t be penalised for its complaint.

Possibly a result of e1b4089?

To Reproduce

Affected PRs:
#1318
#1321
#1322
#1323

Expected behavior

These PRs are not failed on the test.

Yep, my fault.

#1327 is here to compensate this mistake

My reading of #1327 is that this should be resolved - thanks @wowi42 for the fix and @Fizzadar for merging it :)
