Split context vars to avoid circular dependency issue #132

Closed Zapix closed 3 years ago

Zapix commented 3 years ago

There is circular dependency issue coz mtpylon stores on contextvars in same module:

tests/schema/functions/test_login.py:None (tests/schema/functions/test_login.py)
ImportError while importing test module '/Users/aleksandraibulatov/projects/mtpylon-samples/todo-list/backend/tests/schema/functions/test_login.py'.
Hint: make sure your test modules/packages have valid Python names.
