[Do not merge] fix: testing the modified test file with legacy code

[Akanshu-2u]

• ddt decorator and data-driven testing (@ddt.ddt, @ddt.data()) are removed
• Toggle-based testing (IGNORE_LOGGED_IN_USER_ON_MISMATCH settings) is removed.
• Custom attribute assertions (set_custom_attribute mocking) is removed.
• Logger mocking and assertions is removed.
• override_settings usage is removed.
• Complex conditional test logic based on toggle state is removed.

Note: This code is just for testing if the new test code for get_user_if_exists function , works with the legacy code or not. Do not merge the pr , is just for testing purposes.

Reference pr for modified code and test file:
#390
