Unable to refresh JWT auth token

[GabeLambda]

https://github.com/box/box-python-sdk/blob/master/boxsdk/auth/jwt_auth.py#L195

Callers of this method are expecting a tuple of (access_token, refresh_token), not just access_token. This breaks downstream in https://github.com/box/box-python-sdk/blob/master/boxsdk/session/box_session.py#L196, causing clients which use JWTAuth to break on refresh.

Example:

File "/usr/local/lib/python3.4/dist-packages/boxsdk/session/box_session.py", line 196, in _renew_session
    new_access_token, _ = self._oauth.refresh(access_token_used)

ValueError: too many values to unpack (expected 2)

Version: 2.0.0a4

This fix worked for me

Fixed also worked for me but would rather not use a fork forever. Any status on this getting into master?

Fixed via #209

Also fixed in 1.5 via #217.

I just released a new version, 1.5.4, with this fix.
