    token: consistently decode binary types

    Ensure that any binary types unpacked from message payloads
    are correctly converted from binary to text type.

    Under Python 3 msgpack returns the serialized input as a
    byte string. Similar to other msgpack'd values in the payload,
    we need to explicitly decode it to a string value.

    This is specifically more of an issue under Python 3; however
    the decode operation is safe back to Python 2 so there is no
    need to limit the decode codepath to just Python 3.

    Note: the file conflict is caused by patch
    I9529d6bee3e5bb1f618f40f225f69e2ad7e3f64a which is only present in
