Fix with test: _default_jwt_payload_handler doesn't handle dicts as the code seems to imply it should

[oisinmulvihill]

Fixed a bug whereby a dict cause AttributeError even though the _default_jwt_payload_handler is supposed to handle objects and dicts. I've added a test and my proposed fix for this.

all tests pass locally not sure what travis-ci is complaining about :(

Weird, when run elsewhere its causing a problem but not for me, makes it hard to fix this :(

Already fixed by #63 and many others.

I'll pull in your fixes from your branch https://github.com/webstack/flask-jwt/tree/fork into mine then in the meantime.
