Can't login in v2.0.0a3 but can in previous versions

Description of the problem

Attempting to login using fbchat v2.0.0a3 throws an error, see Traceback below. I can login as expected using 2.0.0a2 and 1.9.6…

Someone else has had the same problem, and could also solve by using v2.0.0a2, see https://github.com/carpedm20/fbchat/issues/581

Seems related to the solution to https://github.com/carpedm20/fbchat/issues/413, in particular commit https://github.com/carpedm20/fbchat/commit/079d4093c4f0febf004c6cf8f6972f157833a4f7

Code to reproduce

import fbchat

session = fbchat.Session.login("<username snipped>", "<password snipped>")

Traceback

Traceback (most recent call last):
  File "hello.py", line 4, in <module>
    session = fbchat.Session.login("<username snipped>", "<password snipped>")
  File "/Users/matt/programming/python/patrick2/venv/lib/python3.7/site-packages/fbchat/_session.py", line 290, in login
    raise _exception.NotLoggedIn(error)
fbchat.NotLoggedIn: Password Forgot account?

Environment information

• Python version 3.7.7
• fbchat version 2.0.0a3 (installed with pip install fbchat==2.0.0a3)

The code above is a bit bloated to be committed I reckon. You’re better off just scraping the _js_datr cookie from a new session on messenger.com.

Add it to your session cookies using: requests.utils.add_dict_to_cookiejar(session.cookies, {'_js_datr': js_datr}) or session.cookies.set("_js_datr", js_datr, domain=".messenger.com")

Note to my future self: I managed to get the same error page as you people by inserting an old datr cookie, using that I should be able to improve the error message parsing.
