from_authorized_user_file always returns invalid credentials #501
Description
from_user_info currently always sets the token to None. So a credential created from a JSON is always invalid and must be refreshed.
>>> from google.oauth2 import credentials
>>> TOKENS = 'tokens.json' # OAuth2 token storage
>>> creds = credentials.Credentials.from_authorized_user_file(TOKENS)
>>> creds.valid
False
>>> creds.expiry
>>> creds.expired
False

If a token is available, from_user_info should use it. info.get('token', None)
