fix pylint warnings by fixing a test

[LeXofLeviafan]

I couldn't manage to reproduce the warnings locally… I wonder what's causing the difference 🤔 Turns out pylint misses some checks when it doesn't have access to sources of imported modules. (…Also it only works with Python 3.12 for some reason.)

…Seems like the issue is actually due to pylint bugging out and failing to locate the type during CI testing 🤔

Turns out that's not quite the case; though it's odd that it actually requires a very specific set of conditions to be reproduced.

…More specifically, these conditions are required for this error to happen:

• Python version must be 3.12;
• werkzeug package must be present in the Python environment;
• The files with errors and tests/test_views.py must be linted during the same run.

(The kicker is, the cause of the warning is not within either of the files it's printed out for 😅)

(This one fixes inability to reproduce the error when running lint locally via tox)
