utahta/pythonbrew — Issue #54: pythonbrew off doesn't deactivate the virtualenv (unset the VIRTUAL_ENV env. variable)

because of this while the python is reset back to system python the virtualenv isn't deactivated and hence the confusion that one is still using the pythonbrew python with the virtualenv.
