crashes if payload is nil

[ghost]

If the auth token is corrupt and the payload ends up being nil, the code crashes.

Line 766 of jwt.lua

local val = claim == str_const.full_obj and cjson_decode(jwt_json) or jwt_obj.payload[claim]

Should be

local val = claim == str_const.full_obj and cjson_decode(jwt_json) or (jwt_obj.payload and jwt_obj.payload[claim])
