bufferedconsumer _api_secret problem

[sanderland]

BufferedConsumer has this code:

        # Fixme: Don't stick these in the instance.
        self._api_key = api_key
        self._api_secret = api_secret

Classes that override send without setting these instance vars, such as your recommended AsyncBufferedConsumer, end up generating an error in _flush_endpoint

This could be considered an error in the async package as well (cf jessepollak/mixpanel-python-async#18), but considering you have a FIXME here, I suppose a recent change broke the interaction.

Oh, that's a bummer. Thanks for looking into the cause.
I plan to overhaul this soon in a new major release. Until then, I will prepare a release to fix this snag.

4.8.1 is out, please let me know if it doesn't fix your problem @sanderland.
