Attribute error exception thrown when using PyJWT 2.0.0a1

[vargab95]

PyJWT 2.0.0a1 returns decoded string instead of encoded so the .decode('utf-8') call in

flask-jwt-extended/flask_jwt_extended/tokens.py

Line 29 in 5bd8b1e

encoded_token = jwt.encode(token_data, secret, algorithm,

causes the below mentioned exception.

Got the same issue, so I pinned mine to PyJWT==1.7.1. I think they can fix this by doing the same in their setup.py script.
