Fix api.py logic for corrupt cookie jar and added test cases for the same

[arnchlmcodes]

Added a try/except so if the cookie file is broken or corrupted, it deletes it so the program can start fresh.

also added two tests in api_test.py, one to verify that the error handling works and the file gets deleted if it's corrupt and the other test to verify the recovery works and the bot continues and logs in.

ran the ci pipeline locally and made sure everything works.

closes #443

Wow sorry, this fell off my radar. Sorry about that. The code looks good but I'm worried about the tests.

Could you please tell me what concerns you have regarding the tests, happy to address it right away,
Is it that the new test cases are almost similar, I split them into two separate tests to keep each test focused on one thing, one for the deletion and one for the login recovery, but I can merge them if you'd prefer that.
