Tests for fbchat

To use these tests, put:
- email
- password
- a group_uid
- a user_uid whom will be kicked from that group and then added again
(seperated these by a newline) in a file called `tests.data`, or type them manually in the terminal prompts

Please remember to test both python v. 2.7 and python v. 3.6!

If you've made any changes to the 2FA functionality, test it with a 2FA enabled account
